Text input components with context-menu options

[rat-moonshine]

Text input components like TextInput, TextArea currently not provides standard context-menu options like Cut, Copy, Paste etc. Although keyboard-shortcuts works, for some users with different test-cases the context-menu options are more suitable.

It'd be great if FeathersUI input components provides such context-menu with standard options.

In Flash and Flex, the context menu was provided natively by the TextField component. Unfortunately, OpenFL doesn't provide a context menu yet.

Feathers UI doesn't provide a Menu component yet either. Although, I'm hoping to add one in the 1.4 update.

Context menus in TextInput and TextArea will need to wait until one or the other is implemented first.
