[Feature Request] Make dropdown-input-fields dropdown-only

[newhinton]

When the user opens the "Platform editor" (eg. by clicking the edit button in the bottom right of the platform card), most of the inputs are supposed to be dropdown menus. However, nearly all of them open the keyboard when selected.

Especially on landscape-devices, this leads to the entire screen beeing blocked and in a supbar experience.

I suggest blocking this behaviour where applicable, or at least on the first click.
If i remember correctly, i solved this issue with some of my own AutoCompleteTextView's by setting editable to false on them.

Thanks!
