Removed low-priority file import mode

We’ve removed the low-priority flag that could be used for commands like wti push --low-priority and wti add --low-priority. Historically this flag could be used when uploading a very large amount of files at a lower priority without clogging WebTranslateIt’s file import queue. Nowadays, we can take a very large amount of files to import at the same time and this command is no longer necessary and will simplify our code.

Our wti synchronization tool has been updated to 2.7.4 to remove these commands. You can update it with: gem install web_translate_it.
