Sprunge plugin

This plugin uploads data and fetch URL from the pastebin http://sprunge.us

To enable it, add 'sprunge' to your plugins:

plugins=(... sprunge)

Usage

Command	Description
`sprunge filename.txt`	Uploads filename.txt
`sprunge "this is a string"`	Uploads plain text
`sprunge < filename.txt`	Redirects filename.txt content to sprunge
`echo data \| sprunge`	Any piped data will be uploaded

Once sprunge has processed the input it will give you a unique HTTP address:

$ sprunge "hello"
http://sprunge.us/XxjnKz

Sprunge accepts piped data, stdin redirection, text strings as input or filenames. Only one of these can be used at a time.
Argument precedence goes as follows: stdin > piped input > text strings.
If a filename is misspelled or doesn't have the necessary path description, it will NOT generate an error, but instead treat it as a text string.
