Context menus and tag color customization

[YellowAfterlife]

Tag colors

I've seen that tag colors are loaded from (and saved to) db, but there's no way to edit them without tinkering with the file.

Context menus

A subject of my brief confusion was absence of context menus on the tag list and treeview - separate buttons to change tag name and apply tag to tree item would have seemed like an interesting twist.

Draft

Done:

• Context menu on tag list allows to change tag names and colors.
• Context menu on treeview allows to quickly set tags to items.

Not done:

• Changing tag color requires updating tag-related bitmaps (therefore currently changes take effect on restart). I'm not sure what the right way of dealing with that is (particularly the ImageList for tag list).
• Last tag' icon on treeview' context menu is often amiss the first time it is brought up (is it about SelectObject?).

May or may not be made appropriately due to my limited experience with "raw" WinAPI.

If this looks fine, I can submit a PR. Otherwise would be glad to hear what to do with this.

Thanks, that looks like some nice functionality! Go ahead with the PR, code looks good on first glance.

The two issues you mention would be nice to fix, but sadly I am no WIN32 expert either, so not sure how to fix them. For the color bitmaps, maybe we can restructure the code such that it creates these bitmaps upon opening the stats view? That is slightly better than having to restart? You could even force to close the stats view upon a color change, so the user will reopen it and get correct colors?

Also, you can maybe remove the "rename" button now, since that is redundant. Maybe keep "apply tag to node" since that still may have a function.
