Show the keyboard when selecting Other in Receive.

- Automatically show the keyboard and focus the AutoCompleteTextView when the user selects 'Other...' in the Asset spinner, in the Receive screen.
- Created an extension function for EditText, which requests focus and shows the keyboard at the same time, so that the user can immediately start typing the desired text.
