Move soc/control to soc/logic, so that tab-completion doesn't keep matching soc/content instead.

nickname was moved from Person to User recently.

Add Roles template directory that was missing from r426 commit.

Create package for up-coming Role views.

Minor indentation fix.

Create package for standard Melange controller modules.

Reduce the indent to two spaces per hierarchy level, comment some groups of tags that are related, move #header down by #footer.

Some additional __doc__ comments (with some ideas for future plans) and removal of some unnecessary imports.

Clean up some deletions from previous rearranging that did not get committed.

Fix up the URLs mapping to soc.views.user.profile.edit() and make the site base template (mostly a mock-up) point to /user/profile instead of the old /usr/linkname/profile from the static mock-up.
