Title: Should match 'charset' as well

Comment:
Though it's not mentioned as a matching sample, e.g. 'text/html; charset=iso-8859-1' should also be matched by the expression. It works well with the .NET framework, at least. Here's a one-line version of the expression as well:
^(?<toplevel>[a-z]+)/(?<subtype>[a-z]+)(\+(?<formattype>[a-z]+))?(; *?charset=""?(?<charset>[a-z0-9\-]+)""?)?$
And here's one without the group-naming:
^([a-z]+)/([a-z]+)(\+([a-z]+))?(; *?charset=""?([a-z0-9\-]+)""?)?$
