GUI: Remove trailing spaces in some strings
|Reported by:||jvprat||Owned by:||sev-|
This patch removes the trailing spaces in some strings of the GUI, that will cause confusion to translators.
Those are used to separate right-aligned strings from the next widget. I'll attach another patch in a few that makes the theme to perform that separation so it's independent of the string.
