* createFaces can now create fan/star like faces.

* Cleaned up worm gear code.
* Vertex and face creation process is much simpler now.
* This also prevents double vertices.
* Removed lots of unneeded variables
* TODO: Create "closing" faces for the worm gear.

* Major refractor - removed most of the hardcoded stuff.
* Separated functions into gear, worm gear (and experimental/non-working spokes)
* "Gear" now doesn't have any duplicate vartices.
* New submenu "Gears" (entries "Gear" and "Worm Gear")
* TODO: Prevent doubles in "Worm Gear" (change it so only one row of verts is calculated for each step)
* TODO: Finish/improve spokes code ("add_spokes").
* TODO: Create new "auto-spokes" function that addes a "Gear Spokes" Object for an existing "Gears" obj (either via the "recall" data - this stuff is usefull :-) or by creating 2 objects at the same time.)

* Added full author name.

* Added _lots_ of "telling" variable names ... far from done :-/
* Support "recall" operator.
* @todo: This script definitly needs some comments on what's going on.
* @todo: Lots of hardcoded stuff (also deepcopy) - is there a better way?
* @todo: Do not create "double" vertices in the first place.
* @todo: Is it really a good idea to mix gears & worm in the same operator?

commit 27934 by DingTo: Improved Addons in User Prefs by Keith Boshoff (wahooney) This adds a "description" field to addons (ideally a small 1 liner, with basic info)

[[Split portion of a mixed commit.]]

add pontiac's clever fix for long wiki links to all scripts
links should be pep8 compliant now.

Changed all icons to PLUGIN for consistency.
