Removed Training module for the time being (issue #21)

The training module is incomplete in it's current incarnation.  Removed
it so other fixes in this release can be pushed.
Release 1.0 of Tool module (issue #23)

Finished first release of Tool module.  Replaced existing Tool module
code with code based off of membership plan maintenance module instead
as tools aren't associated with specific members, and the code was much
simpler for the purposes of a straightforward inventory module like
this.
Updated config.sample.inc.php default module links, etc.
