ha! that actually works.

one question - for now it seems I'm forced to edit the bundled 
specifiers.plist to add specifiers to i.e. "subject.body" ?

i.e. I can't just add this to `~/Library/Application 
Support/MailMate/Resources/specifers.plist`:

```
invites = {
         headers = "subject.body";
         specifierRegex = '(.*?):(.*?)@(.*)';
         specifierCaptures = {
             1 = { specifier = "invite-action"; };
             2 = { specifier = "invite-title"; };
             3 = { specifier = "invite-time"; };
         };
        };
```

I have to add this to the bundled: 
`/Applications/MailMate.app/Contents/Frameworks/OakMIME.framework/Versions/A/Resources/specifers.plist`

```
	subject = {
[...]
			specifierCaptures = {
[...]
				  4 = { specifier = "body"; type="noTabs"; parsers = ( "words", 
"invites" ); };
[...]
		};
[...]
     invites = {
         specifierRegex = '(.*?):(.*?)@(.*)';
         specifierCaptures = {
             1 = { specifier = "invite-action"; };
             2 = { specifier = "invite-title"; };
             3 = { specifier = "invite-time"; };
         };
        };
```

notice the `parsers` now have "invites".
