Allow Container::Vertical and Container::Horizontal to have an
external selector, similar to Container::Tab.
This is useful for implementing a menu of menu.

Modify the ftxui::Pixel. Instead of storing a wchar, store a
std::wstring. Now a single pixel can store multiple codepoints.
If a codepoint is of size <=0, it will be appended to the previous
pixel.
Only ftxui::text() is supported. ftxui::vtext support still needs to be
added.
This causes the following CPU and memory regression:
- Memory: Pixel size increases by 200% (16 byte => 48byte).
- CPU: Draw/Second decrease by 62.5% (16k draw/s => 6k draw/s on 80x80)
Both regressions are acceptable. There are still two orders of magnitude
(100x) before the levels where performance/memory concerns begins.

This flag is used to find global functions defined without a previous
declaration. Usually it spots accidental globals, but in this case it
was just missing headers.
Two new elements:
- flex_grow : Expand the element to occupy free space.
- flex_shrink: Minimize the element leave away missing space.
flex = flex_grow | flex_shrink.
Other changes:
- hbox and vbox are now non flexible by default.
- the vtext element has been added to help writting tests.
- Many new tests.
Most CJK users use IME (input method) to type CJK characters. They need
the cursor to be at the correct location, not in the bottom right
corner.
This CL does:
* Move the cursor the focus() element.
* Hide the cursor (and show it at exit)
* Intercept SIGINT to guarantee proper cleanup all the time.
This should fix the second issue mentionned on:
