Limit the memo length to 100 in the Send screen.

Browse source 
- For some reason if we use a memo longer than 107 chars we get an error, to avoid that error we are limiting the memo length to 100 chars using TextInputLayout's counter options to show the current char count and the max char count. If the current char count exceeds the max the TextInputLayout turns to red and the Send button is disabled.
