Favorite maps

[devo1929]

A couple of things done here:

• First of all, when a favorite is created, the user isn't just marking the map as a favorite. They're marking the map for a given game mode as a favorite. So, I created a GameModeMap class that is the instance of a Map for a specific GameMode. This also has a property of IsFavorite to mark that specific instance as a favorite. This collection is instantiated dynamically when the MapLoader runs.
• Convert the "game type" (or "game mode") drop down to a "game filter" drop down. Each item has an "action" or function that will return a list of available GameModeMaps for the filter. The first item is a "favorite filter". All others are simply filters for each possible game mode.
• Convert the "map list" to a "game mode map list". It now lists GameModeMap instances.
• When right clicking on an item in the new "game mode map list", the user has the option to "Add Favorite" for that map. When right-clicking a map that is already a favorite, this option will be "Remove Favorite".
• When viewing the "Favorite Maps" option in the new "game filter" drop down, all listed Maps will be in the form "MapName - GameModeName".
• If a user is viewing the Favorite Maps filter and removes the LAST map from that list as a favorite, the "game filter" drop down will immediately jump to the first filter in the list that does have a map (typically Battle).
• Toggling a favorite is also available from the MapPreviewBox
  • This goes for multiplayer guests, too
