* fix Doc contextmenu not registering commands if scale plugin is not found
* fix TreeView contextmenu commands not working if the mouse hovers DocView
* add keyboard navigation to TreeView contextmenu
* fix incorrect contextmenu predicate
When a command is performed with parameters, those are now passed to the
predicate.
The predicate can then return, after the validity boolean, any other
value that will then be passed to the actual command.
If the predicate only returns the validity boolean, the original
parameters are passed through to the actual command.
This allows predicates to manipulate the received parameters, and allows
them to pass the result of an expensive computation to the actual
command, which won't have to recalculate it.
String and table predicates will now also return `core.active_view`.
The method RootView:on_mouse_pressed was copied in the contextmenu plugin with
a small modification to intercept the mouse clicks of the active view.
This approach is problematic because a relatively large portion of code is
duplicated.
We introduced a function named RootView.on_view_mouse_pressed to let plugins
like contextmenu intercepts mouse clicks in the active area without duplicating
the function RootView:on_mouse_pressed.
* Retrieve scale plugin from lite-plugins
* New implementation of scale plugin and font C API
Introduce two new C API functions, renderer.font.get_size and set_size
respectively to get the font size and to set the size to a new value.
Using these functions we don't need to know the name of the font but
we can just change their size.
Adapt the scale plugin to use the new C API function with minor adaptations
in the logic.
Use smaller step to scale fonts.
Rename font_desc_free function, previous name was misleading as only the cached
resources are freed.
* Add contextmenu plugin from takase
From https://github.com/takase1121/lite-contextmenu
Adapted to show font scaling commands and find/replace commands.

* Fix the cursor flickering with contextmenu
To avoid flickering of the cursor when using the context menu
we add a new function `core.request_cursor` that just take note
of the cursor requested.
The cursor will be actually changed only in root_view:draw() method
only when all the drawing operations are done. This means the cursor
will be changed only once per frame and only the most recent cursor
change request will take effect.
* Remove unneeded scale plugin return functions
