Cannot Translate "Other Amount" because string is not passed through the ts() function

The Label "Other Amount" is not passed through the ts() function, so it cannot be translated.

This String can be found in the file:
CRM/Price/BAO/Field.php
on Line 362.

Currently it says:
$none = 'Other Amount';
It should be:
$none = ts('Other Amount');

I would write a patch for this, but I'm a first time Issue reporter and I'm not sure the process for doing so in Civi, if you could let me know then I'd be happy to submit a patch.

thanks!
