initial commit

staff.py changes:
import django core paginator libs
get user setting for tickets per page
get http GET variables for page selection on three tables
use django paginator to get current page tickets only, and pass those to dashboard.html instead of all tickets

dashboard.html changes:
assign the correct HTTP GET argument to each table

tickets.html changes:
add pagination controls below table div, and pass HTTP GET args back to the URL when clicked
