Nuke xpi-* ports

Legacy extensions aren't supported by Firefox anymore. Very few were
maintained up until last year when AMO stopped hosting files.

Remove Author from pkg-descr

Reset miwi's maintainership per his demand

Hope to see you back! Thank for all the work!

- Stage support

Add NO_STAGE all over the place in preparation for the staging support (cat:
www)

The vast majority of pkg-descr files had the following format when they
had both lines:

Author: ...
WWW: ....

So standardize on that, and move them to the end of the file when necessary.

Also fix some more whitespace, and remove more "signature tags" of varying
forms, like -- name, etc.

s/AUTHOR/Author/

A few other various formatting issues

- Get Rid MD5 support

- Remove DEPRECATED
- Take over maintainership

Approved by:    chinsan (old maintainer)

- Set DEPRECATED with my xpi-* ports at first.
  They could installed and updated more easily by user's browser(firefox).

- EXPIRATION_DATE on 2009-01-31

- Take all xpi-* maintainership

Reset infofarmer due to maintainer-timeouts and no response to email.

Hat:    portmgr

- Update to 0.9f.2

- Update to 0.9.f

Add port www/xpi-infolister:

InfoLister is an extension for Mozilla Firefox, Mozilla Thunderbird,
