User field adjustments

This is missing the field organization adjustments because I am unsure of how this info will be stored.

This uses the install hook to adjust the fields on the user profile.

I'm not sure what to do with the features -- if I need to do anything at all. Advice is most appreciated!
Added watchdog() calls and checked to see if drush_log() function exists.

Also removed drupal_flush_all_caches(). I think this is unnecessary and I noticed issues when enabling the module thru the gui. It looks like there's an unrelated error coming from the views module when clearing the cache. I'm not sure of the problem exactly.
migrate_users: I removed the duplicate drush_log() when watchdog() is used.

I kept some drush_log() cause I didn't want the log to fill up with notice-type info. Also changed almost all of the remaining drush_log() to 'notice'.
migrate_users: drush_log() Free! :)
Merge pull request #10 from mirie/migrate_users

Migrate users: removes user fields and and changes a couple of text fields to taxonomy reference fields. Also creates terms to replace the comma separated text. Note: manual cleanup of some terms (like ones that are sentences!) is still necessary.
