• Added TLOLocalization.swift which is a Swift implementation of the localization system. TXTLS() and its sister functions are bridged to this implementation.
• The TLOLanguagePreferences class no longer exists. This class was used only as a convenience to TXTLS() and its sister functions. I don't know of any and/or why a plugin may access these, so they were not deprecated.
• The TLOLanguagePreferences files have been renamed to TLOLocalization as the latter better suites its purpose.
