Added more configurable options. Removed some annoyances.

[optroot]

Allows for some configurable options for when auto-pairs trigger:

• Only trigger when there is whitespace to the right
• Only trigger when there are only close-tags and whitespace on the right
• When a line is not balanced, insert close-tag before skipping over
  f(g(x|) -> press ')' -> f(g(x)|)
• Never skip over tags
• Never skip except over quotes
• Never jump lines

See the commit changes to the readme for more details

And some minor bugfixes, and a debug option.

@optroot "Only trigger when there is whitespace to the right" <-- Thank you

Only trigger when there is whitespace to the right

This should not be an option, this should be default behavior! And I mean it. No one wants to add a pair of quotes right before a word. @jiangmiao please merge this and make it default.

@jiangmiao please give some attention to these prs, there's a bunch of them wanting the whitespace behaviour and it keeps coming back.

No one wants to add a pair of quotes right before a word.

Well, I kind of do: press quote and then M-e, and the word is wrapped in quotes.
