+ Renamed "Messages" to "Chat Settings"
+ Moved the chat mentions to this tab
+ Added boarder round macro settings

When being mentioned in a post with '@username' you will now see the entry highlighted. This
helps to see when someone is talking to you. It work across the main
chat, in game and in private chat.

+ Moved Icons to the top. You can now see all options.
+ All SVGs now have a background (GO! was missing one).
+ All SVGs now have the same background (General had one of its own)

Moved the button from the paths section to be below the "Download high-quality card pictures" checkbox. Button now reads "Reset/Clear Downloaded Pictures". Removed "Path to"s from card/token database, hand/stack/table/player info background, and card back labels.

Added notification messages informing users of the success or failure of clearing downloaded images.

Added a button and the functionality to clear all downloaded images (all images within subfolders at picsPath/downloadedPics) under Settings.

Probably settingscache would have been the correct place for the enum,
but keeping it in the same class/file where price sources are defined

* the previous PriceUpdater class has become abstract
* BLPPriceUpdater inherits the old code for blacklotusproject.com
* DBPriceUpdater is a new implementation for deckbrew.com
* add a setting to choose between the two

Better error message and allow the user to still connect
