Merge branch 'master' into blurg-test

Due to unforseen naming conflicts, the project has been rebranded under the ReFuel
umbrealla and will now be referred to as Dashboard from now on. Other changes will
occur to suit the library more for the engine whilst keeping the freestanding
nature of the library.

Rename folder.

Rename to Dashboard.OpenTK

Rename to Dashboard.Media.Defaults.

Do the last renames and path fixes.
