[Mono-dev] Patches for mono-winforms

I reported a few of them in Bugzilla, but I wasn't sure if that database got any attention, e.g. the DataGridView.SelectionRows bug wasreported months ago and go no reply.  I don't currently have an account on GitHub; if I absolutely must have one, I'll go make one, but I wasn't planning to do that unless I started making tons of changes or something.  Also, how does one write a unit test for something that has to be verified visually (e.g. fixing ToolStripItem.BackColor) or via user interaction (e.g. fixing DataGridView.SelectionRows)?  So I suppose, yes, I need help :-)

Thanks for your work.

If I'm not mistaken, you reported each of these bugs, right? At least I
could find the two first ones in bugzilla, but didn't go further. Anyway, I
suggest you make pull requests for each bug separately, specifying the bug
number. Also, please include unit tests with each patch, highlighting what
was fixed. I know it's more work, but it will make commiters more confident
with your changes, and will guarantee no one will ever break these parts

Let me know if you need help.
