     - Fixed a bug where Directories were not being created

1/21/2013:
     - Added opera plugin support.
     - Fixed a bug where directory selection would default to ~/Downloads if non-exsistent path was given.
     - Removed support for update numbers with less than 2 digits. Now 1-9 must be input as 01-09.
