42b6d1fc3c fix: fixes a logic bug and allows setting Arg::number_of_values() < 2 
Allows setting `Arg::number_of_values(qty)` where `qty` < 2. This allows
things such as `Arg::number_of_values(1)` in conjuction with
`Arg::multiple(true)` which would make invoking the program like this
`myprog --opt val --opt val` legal, but `myprog --opt val1 val2`
illegal.

d0da3bdd9d feat: allows waiting for user input on error 
In order to pause for user input on error use `.wait_on_error(true)` but
it's important to note that this is *not* recursive through subcommands.

This is useful on Windows when a user mistakenly opens an application by
double clicking it, instead of using the command line or if using a GUI
shortcut to run a program.

Kevin K
eb1d9320c5 feat(Help and Version): allows overriding h/v short and changes default ver short to -V 
The new default short for version is `-V` (capital). This is a "breaking"
change at least for documentation.

If the old lowercase `-v` is desired you can manually override with
`App::version_short("v")`

The help short can also be overridden now too.

30fa87ba4e feat(macros): arg_enum! and simple_enum! provide a Vec<&str> of variant names 
You can now use  ArgName::variants() to get a Vec<&'static str> of
vairant names (Nice for Arg::possible_values()). It's not as good as
implementing Iterator for the enum, but that can't be done without being
able to concat AST tokens in order to make an "EnumIter" type which
implements iterator and keeps track of when to yield None. But the
overall intent of this issue was to be able to iterate variant names,
which is now possible.

0535cfb0c7 fix(did-you-mean): for review

1cc2deb291 feat(did-you-mean): for possible values 
There now is a single method which deals with formatting the
'did-you-mean' message, supporting different styles to cater all the
various needs that have arisen thus far, with enough potential to be
easily extended in future through a little helper-enumeration whose
variants can possibly take values.

*NOTE*: We might still want to have a look at where the did-you-mean
message should be located for best effect.

627ec103c9 refactor(app):dedup possible_values error-handling 
This is done in preparation for adding suggestions.

**NOTE**: We will now always use the ...
`"\"{}\" isn't a valid value for '{}'{}"`
... format, even though in one occasion, only a ...
`"\"{}\" isn't a valid value for {}{}"`
... format was used.

Hope that's alright and not breaking the world. At least, it doesn't
break any of the existing tests.

06e869b518 feat(did-you-mean): for subcommands 
If an argument is not understood as subcommand, but has a
high-confidence match in the list of all known subcommands, we will use
this one to print a customized error message.

Previously, it would say that a positional argument wasn't understood,
now it will say that a subcommand was unknown, and if the user meant
`high-confidence-candidate`.

If the argument doesn't sufficiently match any subcommand, the default
handling will take over and try to treat it as positional argument.

* added dependency to `strsym` crate
* new `did_you_mean` function uses `strsim::jaro_winkler(...)` to look
  for good candidates.

without multiple(true) set (and assuming 2 values) -o val1 val2 is only
allowed one time, but with multiple(true) set, -o val1 val2 -o val3 val4
is allowed.

Breaking Change

Instead of requiring a Vec<&str> for various Arg::*_all() and
Arg::possible_values() methods this
commit now requires a generic IntoIterator<Item=AsRef<str>> which allows
things such as constant arrays. This change requires that any
Arg::*_all() methods be changed from vec!["val", "val"] -> let vals =
["val", "val"]; some_arg.possible_values(&vals) (or vals.iter()).

fd61615d1a perf(matchedargs): remove unused vars and String->&str 
This commit increases the performance a bit by using string slices
instead of owned strings. The trade off is that code previously written
to handle all the argument parsing in a speratate function and return
only the ArgMatches must be re-written to add a lifetime specifier:

Old code 'fn handle_args<'a>() -> ArgMatches<'a>' needs another lifetime
specifier added, so now 'fn handle_args<'a, 'b>() -> ArgMatches<'a, 'b>'

Breaking Change
ArgMatches::usage() now returns a slice (no longer an Option<&str>)
This is to improve ergonomics, as there should always be at least a
default usage statement, there should never be None
