Added "cyrillic fix" option

[Kvis-Dev]

Added "cyrillic fix" option, so users who have cyrillic keyboard layout don't have to switch layout to use this extension.

Thanks for your work, but I have some different opinions.

The function VKeyboard.getKeyChar is mainly used to compare its result with a user's mapped keys and link hint characters, and all of these keys and characters can be modified on the Vimium++ Options page.

Then, a user just need to add new key bindings into "Custom key mappings" and replace the "Characters used for link hints" with what's in the wanted keyboard layout. For example:

// Custom key mappings
map к reload
map а LinkHints.activate
map с previousTab
map м nextTab
map ш focusInput
......

// Characters used by link hints
фывпролд

The above should fix many keyboard layout issues, and as for the visual mode, mapKey directive is useful (e.g. mapKey м v). Although currently mapKey will also affect normal key mappings and make it too complicated to use both map and mapKey meanwhile, I'm reworking it soon and it won't be a big problem.

And then maybe the only left issue is some ede usages like translating <c-[> into <esc>, I'll fix such cases whenever they're found.

====================

Some advices about your code:

• your cyrillics list doesn't consider about upper cases of characters
• I'm trying to make source files in the lib folder independent, so VKeyboard should not use VSettings (you may set VKeyboard.*** in frontend.ts: requestHandlers.reset.

Closed, because I've merged the whole logic about ignoreKeyboardLayout in https://github.com/philc/vimium. Thanks anyway for your contribution.
