changed how the mod url works:

 - it is now independent from the nexus mod url
 - it can be set in addition to having a valid mod id
 - both urls can be displayed in the context menu
re-arranged some of the widgets on the nexus tab
added a track button
added a custom url checkbox and open in browser button
added a max-width to the browser

+  // there are several cases to handle to make sure no data is lost and to
+  // determine whether the user has set a custom url before:
+  //
+  //   1) some mods have an incorrect url set along with a valid mod id;
+  //      there is apparently a bug with the fomod installer that can set the
+  //      url of a mod to a value used by a _previous_ installation
+  //
+  //   2) it is possible to set the url even if the mod id is valid, in which
+  //      case it is saved, but never used in 2.2.0
+  //
+  //   3) opening the mod info dialog on the nexus tab for a mod that has a
+  //      valid id will force the url to be the same as what the plugin gives
+  //      back
+  //
+  // the algorithm is as follows:
+  //   always read the url from the meta file and store it so this piece of data
+  //   is never lost; the problem then only becomes about whether to enable
+  //   hasCustomURL
+  //
+  //   if hasCustomURL is present in the meta file, just read that and be
+  //   done with it
+  //
+  //   if not, then the flag depends on the mod id and the url
+  //      if the mod id is valid, the custom url is disabled; although the url
+  //      could be _set_ by the user when a mod id was valid, it was never
+  //      _used_, so the behaviour won't change
+  //
+  //      if the mod id is invalid, the url should normally be empty, unless the

+  //        the user visited the nexus tab, in which case the url was set
+  //        automatically, but then the id was manually changed to 0
