Why aren't certain buttons translated? (SAVE, CANCEL, APPLY, etc.)

There are several common buttons which belong to the internal Qt development framework. These include the SAVE, CANCEL, APPLY, and other similar buttons. Because of this, the text strings for these buttons are not included in xTuple .ts files--and the strings cannot be translated using the Translation Portal. Qt does provide translation files for these common strings, however. These translation files are included with the Qt SDK's that can be downloaded off the web. For example, Qt's Spanish translation file, which is named "qt.es.qm", can be downloaded and then installed in the same directory where your other xTuple translation files are located.
