Make setSelection safe

[planarvoid]

Fix

We're having occasional issues when the setSelection is called out of bounds of the text. While it would be better to fix the underlying issues, I think this is a safe approach to handling this. What usually crashes the app is something like this:

• Preserve cursor position N at the end of text
• Set the cursor position to 0
• Do some modification to the text that shorten the text to N - 1
• Try to set the cursor position to N
• Crash because text length is N-1 < N

This solution handles that case and if this happens, sets the selection to N-1 instead. I can't think of a case where this might be an issue but let me know if you think it's unsafe.

Make sure strings will be translated:

• If there are new strings that have to be translated, I have added them to the client's strings.xml as a part of the integration PR.
