Consolidated feature requests

[Former user]

Hi, just some feature requests for your consideration.

• Resize calculator - this is in AVSPMod (see attached screenshot), takes the input resolution and other target params (like blocksize) and lets you adjust a slider to help choose a good target resolution.
• New hotkey (or updated behaviour): Toggle line commenting. So I can just use ctrl + / to toggle comment/uncomment currently selected lines. Currently if you bind both comment and uncomment to the same key it puts a warning in the log. Desired behaviour: If you select multiple lines - some of which are already commented - and use the toggle button it first toggles them all commented, and the second use uncomments them all.
• New hotkey: ctrl+up/ctrl+down to move the selected line up or down the script. Really handy for when you're experimenting with filters. ctrl+d to copy a line, then ctrl+up to move it into the previous block.
• Flake8/PEP8 support, so on save it'll throw a warning about line lengths, etc. Could be merged with the check-script function where it just runs flake8/pep8 in the background on save or refresh.

Thanks for such a great tool!

Should be ctrl+shift+up/ctrl+shift+down. ctrl+up/ctrl+down are already used for highlighting.

Please don't create consolidated requests. Atomic request issues are more simple to track and resolve.
