feat (pattern-editor): allow for copying single row when no selection is available

[henrikvilhelmberglund]

This pull request aims to add a feature to allow for coping a single row when no selection is available.

I always thought it was a bit annoying that Ctrl+c without a selection didn't do anything. Now it does something, it copies the entire row at once.

There is a crash if you copy a row without a selection, paste and then press delete, not sure what's going on there so I'm marking this as draft for now.

(If applicable) This pull request improves upon and supercedes #<PR number>.

So time to get back to this I think, what I've seen so far: (debugging this causes ctrl c and ctrl v to not do anything, very cool)

• When pasting after copying without a selection ClipInfo.EndColumn is set to 15 which is not a real value
• After that GetSelectColumn() is getting 32768, it should probably not be called at all since nothing is being selected
• After that CopyNoteSection() has an end value of a few millions which then causes problems with the loop below and crashes the program.

I think I'll need to split copying with a selection and copying without a selection for things to make sense.

Should work now, there's an assert in debug when you paste from a copy without a selection though, not too sure what to do about that.

Usage:

• Navigate to a row
• Press Copy (no selection needed)
• Navigate to another row
• Paste, the whole row from before is pasted
