Added a keyboard shortcut to toggle the overlay. The default keybinding is \ (backslash) and can be changed in the 'Keyboard configuration' menu in Options, under a new Heat Map section.

Overlay opacity and update speed can now be configured in Mod Settings dialog.

* Change icon to a thermometer
* Fix .NET targeting framework, hopefully fixing overlay colours in Linux.
