* Added a debug logging method, and added debug output to most methods.
 * Added associated options and a menu for debugging: A debug menu (which is not visible by default), an option to show the debug menu, and 3 debug options:
 *  -Clear old logs: Deletes any but newest logs. (Program automatically deletes oldest log when creating a fourth log, for a max of 3 at any time.)
 *  -Debug logging: A check state menu item that toggles creating log files.
 * Added a method that cleans up older debug logs. Only cleans up logs when we have more than 3 logs, or user forces a clean-up.
 * Added some extra internal documentation and comments.
 * Added a requirement for the program to be able to find a version file where the user is trying to say their game directory is.
 * Added error handling for the background worker. Tells the user there was an error, and to upload their log. Writes out exception info to log file, and enables debug menu.
 * Added a menu option to open the program's installation directory.

 * Changed the screen position that the updater uses when it starts up.
 * Changed where the program stores a lot of its internal information, so as to prevent users from accidentally changing something they shouldn't.

 * Fixed a soft-crash caused by the updater trying to move a file to a new directory introduced by a patch.
 * Fixed a credential issue that would happen if the program crashed, which made the user unable to use the MEGATools application set.
 * Fixed an issue where the program wouldn't delete the base game archive if the user was trying to update to a version that has a live patch, and the download was interrupted.

 * Removed the program resetting the download directory to install directory if the user set a location, tried to change it, but pressed cancel.
