PATCH: Add a much simpler alternative to using url-quote-magic + bracketed-paste-magic

[Mikael Magnusson <mikachu@gmail.com>]

Now that we have more control over the yank highlighting, we can handle pasted
urls directly, instead of mucking around with pretending we don't know which
text was pasted together, then trying to reverse engineer this fact from it looking
like a url. This function simply looks at the first few characters and if they
match the configured schemas, then the paste is quoted.

It handles NUMERIC to quote, but not any weird vi or newline stripping stuff.
