A "simple" regex to parse mime types. Handles all commonly occurring parts of a mime type string such as:

• Type
• Subtype
• Subtype's with an extra extension (e.g. svg+xml) (Optional input)
• Multiple parameters (Optional input)

Tested with:

• application/text
• image/svg+xml
• image/svg;q=0.9,/;q=0.8
• image/svg+xml;q=0.9,/;q=0.8
• application/vnd.uplanet.listcmd-wbxml;charset=utf-8
