Support showing ctrl, alt, win keys pressed down without any other key

[bfritscher]

• Removed filtering of modifierkey to allow to handle them in ToInputs.
• Filtered triggering of modifier display for modifierkeys themselves in
  ToInputs.
• Exposed IsModifierKeyPress as static to be used in KeyPress and
  Messages.
• KeyPress.HasModifierPress returns false if key is a modifierkey itself
  (allow the merging in Message).
• Message disable repeat counting incrementing for modifierkeys
  themself, but still handling their repeat, in order for them to keep
  showing while keydown.

This should partially solve issue #154
Note sure about the sticky key part on mac.

after integrating it with my other changes i found there are bugs, and found another solution, but it now seems to fail the tests :-(

But a side effect is that it now support issue #76

Hey @bfritscher,

I haven't forgotten about your PRs, I've just been busy with some other things lately. I should have some time over the next week or so to sit down and review your PRs.

My apologies for the delay in getting to them!

Thanks,
henrik

@alfhenrik No problems :-)
And I understand that they are a bit more complex. They also might need some test cases, in order to cover edge cases. Happy to do some changes after your insights.
Best regards,
Boris

To solve this issue would be so helpful, to show CTRL SHIFT stand alone. Any progress maybe?

I was looking to get a counter on the modifier keys specifically, but there seems no option to do so...

Hi, @bfritscher I really appreciate your work to add the mouse highlight, but the https://github.com/bfritscher/carnac/tree/v3-beta seem have a bug, like #173 descripe, when hold two keys and left click, but it dosen't show any key just the mouse icon.
