poire-z e699a1ee22 TextBoxWidget: use xtext for text shaping
Alternative code to size, split lines and draw text with
the help of the xtext Lua C module.
Enabled by default (can be disabled via an added menu
item in "Developer options").

New properties can be specified by calling widgets, only
used when xtext is used:
- lang: use specified language instead of the UI language
- para_direction_rtl: true/false to override the default
  direction for the UI language
- auto_para_direction: detect direction of each paragraph
  in text
- alignment_strict: prevent the inversion of the specified
  alignment= that is done when a paragraph direction is
  set or detected as RTL.

Also: fix possible memory leak (present even when not using xtext)
by calling :free() in onCloseWidget() like it's done in ImageWidget.
