Moved lib/generators/templates to lib/generators/surveyor_gui/templates

This directory was erroneously placed directly in the generators folder.
Add install_generator to setup surveyor_gui.

	Rakefile: The Rakefile calls both surveyor and surveyor_gui install
	generators.  It also creates a populated testbed.  That needs to
	be moved into a seperate task later.

	install_generator: copies db migrations, routes, and assets to the
	new app
modified .gitignore to include testbed
