Avoid Unnecessary Rountrips

[Tygre]

When rating a module, there will be two calls to the Web server: one to rate the module and one to get the rating (i.e., to make sure that the rating was saved!). The second call is quite unnecessary...

[Tygre]

The getting of the user/communicaty ratings was silly and led to many useless calls. Now, it's done once and only once per file and the results are shared.

Removed lots of papercuts. Fixed #96, #99, #106, and #107.
