Adding an admin servlet

instead of .../mygig_planner.html?....
.../admin/generate/User/25 to generate 25 users ( you can change the
amount, but the word user must be capitalized and there must not be any
spaces.
.../admin/generate/Availability to add random days of availableness for
random users
.../admin/clear/User to remove all users
.../admin/clear/Availability to remove all availability dates

For exmaple for me its:
http://127.0.0.1:8888/admin/generate/Availability
