Add Ctrl+Shift+Arrow and Ctrl+A shortcuts to select text in the TextBox widget

[koutoftimer]

It is a feature request to add support of common shortcuts for editing text in TextBox widget:

1. Ctrl+Shift+Arrow - to select/unselect a word (everything untill next whitespace) according to direction
2. Ctrl+A - to select all text

[ForLoveOfCats]

Ctrl+shift+arrow support is supported in current master as of #1076
Ctrl+a is also supported but I'm not sure when that was added

That sounds like you have an older Rust. We're pretty enthusiastic about using newer features on stable.

Rust 1.46 stable works. Thanks.
