More or less did a complete rewrite of the plugin, replaced the use of tracker name by use of tracker ID for permission flags, added a patch to RolesController for translating and displaying names, revamped the IssuesController patch so that now it rejects invalid trackers properly on edit/update/create, removed the javascript bit since it didn't prevent direct updates
Added handling code for the module not being used, added an exception for updating if no tracker ID, or tracker ID not changing
Fixed comparison with old tracker ID in update check, and allow admin to update trackers
Merge pull request #21 from darksoul42/redmine2
