Various improvement for Fields integration with devel_generate. Now populating Fields attached to all of nodes, users, comments, and terms. Also respecting field settings like max/min and precision/scale for number and text fields.

Support skip-fields in generate-content since some fields like taxonomy can huge allowed values lists and those can memory crash.

Add devel-reinstall command for quickly disable/uninstall/enable a given module. More development related commands coming.

Major new functionality, analyzing the results of the new hook_node_access_records_alter() and hook_node_grants_alter().
General clean-up.

Added try/catch for the other db_insert().
Minor code formatting.

#687788 by moshe weitzman. Support file and image fields in D7's devel_generate. Also massively refactor devel_generate into a new directory below devel and lots of little include files for each Field type.
