Improve the keyboard opening position

[Thomas Di Meco]

It could be smart to open the keyboard to not hover the target text view, but for example on the left if possible, and on the right if not. A keyboard could also have a preferred direction by default.

Yes :) It should also not go out of the screen. I think currently if the selector is too long it will show below it, or has this changed?

Now you can choose the preferred opening direction (by default it's BOTTOM). The keyboard tries to open in the given direction. If it can't, it tries the opposite direction, then the 2 others (if none of these work, it opens hover the parent).

The selector now opens the keyboard on top by default to avoid to hide the content.

Tell me if it's ok! :)

Great work! Thanks!

Merged.
