* [DRun] Introduce data structure changes for Link desktop entries
From the [freedesktop spec][1]:
> This specification defines 3 types of desktop entries:
> Application (type 1), Link (type 2) and Directory (type 3). To allow
> the addition of new types in the future, implementations should
> ignore desktop entries with an unknown type.
This commit adds an enum to capture these types, and adds `type` to
DRunModeEntry.

* [DRun] Sanity check Link entries and capture the URL
Note that we're introducing some logic that will differ depending on
the Desktop entry type (Application or Link). The logic is:
- if entry is Application type,
- then Exec is required
- and the value is saved in .exec
- and drun_mode_result calls exec_cmd_entry
- if entry is Link type,
- then URL is required (but is not saved in the DRunModeEntry)
- and drun_mode_result calls new function launch_link_entry

* [DRun] Launch desktop links via xdg-open
Note that this introduces a new dependency on xdg-open, which may not
be installed. In that case, rofi will display an error dialog
with something like:
"Failed to execute child process xdg-open (No such file or directory)"
which hopefully is explanatory enough for folks.

* Make drun options comments consistent and add a bit of whitespace
* [DRun] new config option drun-url-launcher for opening links
In previous commit, this was a hard-coded string.

* Improved background draw code
- Better to read (precalculated coordinates)
- Unnecessary line_to in the end
- Don't use radius in calculations if zero
* Background draw - separate rounded rect function
* Limit background & border overlap size
Overlap is too good against artifacts when stiching antialiased areas to
be avoided, unless intermediate image is used for additive stiching. But
it doesn't look good with transparent borders, when overlaping background
is visible. It seems, that 1px overlap is right enough to completely
prevent artifacts. Though things may differ if one if side is 1px or
even 0px, while adjacent is still enough thick.
* Style: alignment, less noise, limit var scope
* style: remove extra space
* feat: handle xrm_Char in config parser
Handle the `xrm_Char` case in the (rasi theme) config file parser. This
should properly handle configuration like
```
matching-negate-char: "\0";
```
and
```
matching-negate-char: "-";
```
* refactor: don't handle mem in xrm_Char case
`mem` shouldn't ever be set when `XrmOption` is `type` `xrm_Char`.
Therefore, there is no need to check it and free it. Remove that logic.
* refactor: further condense logic
* style: s/Everythin/Everything/
* style: s/parsing an section/parsing a section/
...and missing period.
* feat(lexer): add CHAR token
Add a `CHAR` token that takes things of the form `'<char>'` or some
specific backslash escape sequences like `'\''` and `'\0'`. For now,
save it as a `T_STRING`.
* refactor: define char property type
* feat(parser): add cval and T_CHAR
* refactor: use char property for xrm_Char
Instead of using strings for property elements of type char, use
characters, which were recently added to the grammar.
* Man pages: Add version and dump-* options
* Man pages: Add -display and -markup to rofi.1
* Man pages: Use the metavariable in -async-pre-read
* Man pages: document the dmenu -w option
* Man pages/help: correct -only-match description
* Man pages/help: -normal-window does not only apply in dmenu mode
* Man page: modi are lowercase
Entering the modi as the man page had them would not work
* Man page: minor formatting/grammar tweaks
* modi and command names are `backticked`
* rofi is **bold**
* other man pages are **bold(1)**
* Pango is capitalised according to their own website.
* Option arguments are *like1*,*this2*
* Man pages: fix Pango markup link
