User selectable line colors and line types

[UnmannedAnders]

Hi Henrik,
When loading the 1.0.99.0 pre-release the OpenStreetMap tile loads correctly. There were how ever some other minor sw bugs in the pre-release version. Example, when typing a new title this does not appear until a new panel is opened.

However, this improvement calls for the possibility for the user to manually select line colors and also different line types such as dashed lines.
