fix(widgets/table): take borders into account when percentage and ration constraints are used (#385)
* Fix percentage and ratio constraints for table to take borders into account

Percentage and ratio constraints don't take borders into account, which causes
the table to not be correctly aligned. This is easily seen when using 50/50
percentage split with bordered table. However fixing this causes the last column
of table to not get printed, so there is probably another problem with columns
width determination.

* Fix rounding of cassowary solved widths to eliminate imprecisions

* Fix formatting to fit convention

c4cd0a5f31 fix(widgets/chart): use the correct style to draw legend and axis titles
Before this change, the style of the points drawn in the graph area could reused to draw the
title of the axis and the legend. Now the style of these components put on top of the graph area
is solely based on the widget style.

fix(widgets/barchart): fix chart filled more than actual (#383)
* Fix barchart incorrectly showing chart filled more than actual

Determination of how filled the bar should be was incorrectly taking the
entire chart height into account, when in fact it should take height-1, because
of extra line with label. Because of that the chart appeared fuller than it
should and was full before reaching maximum value.

* Add a test case for checking if barchart fills correctly up to max value

ecb482f297 fix(backend): move the cursor when first diff is on second cell
Both termion and crossterm backends were not moving the cursor if the first diff to draw was on the
second cell. The condition triggering the cursor move has been updated to fix this. In addition, two
tests have been added to avoid future regressions.

0ffea495b1 refactor: implement cascading styles
- merge `Style` and `StyleDiff` together. `Style` now is used to activate or deactivate certain
style rules not to overidden all of them.
- update all impacted widgets, examples and tests.

5a590bca74 chore: enable clippy on all targets and all features
- Remove deny warnings in lib.rs. This allows easier iteration when developing
new features. The warnings will make the CI fails anyway on the clippy CI
stage.
- Run clippy on all targets (including tests and examples) and all features.
- Fail CI on clippy warnings.

6cb57f5d2a feat: add stateful widgets
Most widgets can be drawn directly based on the input parameters. However, some
features may require some kind of associated state to be implemented.

For example, the `List` widget can highlight the item currently selected. This
can be translated in an offset, which is the number of elements to skip in
order to have the selected item within the viewport currently allocated to this
widget. The widget can therefore only provide the following behavior: whenever
the selected item is out of the viewport scroll to a predefined position (make
the selected item the last viewable item or the one in the middle).
Nonetheless, if the widget has access to the last computed offset then it can
implement a natural scrolling experience where the last offset is reused until
the selected item is out of the viewport.

To allow such behavior within the widgets, this commit introduces the following
changes:
- Add a `StatefulWidget` trait with an associated `State` type. Widgets that
can take advantage of having a "memory" between two draw calls needs to
implement this trait.
- Add a `render_stateful_widget` method on `Frame` where the associated
state is given as a parameter.

The chosen approach is thus to let the developers manage their widgets' states
themselves as they are already responsible for the lifecycle of the wigets
(given that the crate exposes an immediate mode api).

The following changes were also introduced:

- `Widget::render` has been deleted. Developers should use `Frame::render_widget`
instead.
- `Widget::background` has been deleted. Developers should use `Buffer::set_background`
instead.
- `SelectableList` has been deleted. Developers can directly use `List` where
`SelectableList` features have been back-ported.

94877f4e7e Use constraints for table column widths
This allows table column widths to be adapted more and scale with the
UI.

The constraints are solved using the Cassowary solver. An added
constraint for fitting them all in the width is added.
