EnglishV4MultiIT keyboard layout

[yuroller]

I created a layout with Italian accented chars on the basis of the EnglishV4 layout.
It it similar to THUMBKEY_EN_V4_MULTI_KEYBOARD_MODES for SV language, but with Italian chars only.

Looks good, thx!

You need to run ./gradlew formatKotlin to pass lint.

After fixing the sorting of the import statements, shall I retire this pull request and do a new one or can I append a commit?
BTW: I just copy pasted the English Keyboard layout to a new file and made my modifications; maybe if there is the ability to apply a layer (e.g. italian accented chars) on top of an existing layout (e.g. englishV4), in the long run could make maintenance easier.

You can add as many commits as you like to this PR.

Adding layers and conditionals to the definition files could get way too complicated too quickly. If there are any future bigger changes, you'll have to make a PR to edit the keyboard you just added.
