[Meta] Upstream issues that ought to be fixed in OTE

[JuBan1]

These upstream issues concern functionality that OTE is meant to replace. These make good candidates for future work.

• #148 - Vertical line at a specific column
• #324 - Option to set page width for a document in notepadqq ?
• #420 - Matching word highlighting must highlight matching whole words only
• #234 - Replace "in selection" functionality is missing
• • Note: Search/Replace interface is due for a rework. The functionality exists for the most part.
• #628 - Cant collapse Pyton Block With Comments at the end
• • Note: Function/conditional blocks can't be folded in Python at all it seems.
• #745 - Undoing regex replace on multiple matches affects only last match
• #734 - Ability to mark lines as in notepad++
• • Note: Needs a fair bit of change to Nqq's code. Might want to add parameters to OTE's search/replace functions for this.
