Highlights the current line in the editor; really simple.
Now also supports multi-line selections!
You can now also underline the the current lines thanks to @sniperbat. This isn't enabled by default, and you can edit the colour and type of line.
I've added some basic options to change the colour and opacity for the line. Also, It's now possible to Enable and Disable the line.
- Add menu and hotkey mappings for enabling/disabling the highlight.
