DTube Bug - Tagging when uploading a video

I noticed a few weird bugs with the tagging system... Wasn't too sure how to let folks know, so thought I'd write a short article detailing what I've noticed:

1. Tags cannot be edited - ie, while typing a tag, if you misspell something, backspace on a keyboard does nothing. I'm using Windows 10 on a desktop.
2. Tags cannot be deleted once created - pressing the little "x" does nothing, delete does nothing, and backspace does nothing.
3. Tags can only contain one word - which creates issues with things such as software names (ie, I created a tut that's about a function in Premiere Pro cc 2018 - but "Premiere Pro cc 2018" can't be a single tag). Space is used as the tag separator instead of commas, or semi-colons.
4. The error message "invalid permlink character ${s}" is kind of useless at explaining that the issue is with the tag. Trial and error helped me figure that one out.
