Switch to using curl and regular expressions to generate a local cache
file so that we don't need to hit pypi.python.org every time.
This (obviously) results in a massive speed improvement, especially if
you spawn new shells frequently.
This also makes the autocompletion work for me, it didn't before. (pip
would always time out.)
And, also, for fun: This allows you to explicitly set which pip indexes
to use. Technically the old version of the plugin should have had this
behavior automatically -- without having to do more than configure pip
-- but the install completion never worked for me so this is a net gain
in functionality.
* -r, --record now looks for a local file instead of trying to cache
the entire package index
* add --editable because it's useful
* add --single-version-externally-managed because it is too long
* add --record and --root because they're required by
--single-version-externally-managed
