Implement "look up issue status"

(All tables which include created and updated)
1. created date problem: create date format has a problem when update
time changes
"template" : '#=convertTime(created)#'
NaN/NaN/NaN NaN:NaN:NaN
but create time is not changed in the database

(issues table)
2. uid can not be created in issues table

3. each cell only can be editted once

4. when creating a same issue(same title, description pid), it will
display an empty row(not write into database, old problem, see it before
the http
200 problem)

(session table)

5. it seems that there is a build-in sessions table, so we keep to use
'session' table instead of 'sessions'

6. uid can not be created in session table

7. each cell only can be editted once

(occurences table)

8. each cell only can be editted once

9. uid can not be created in occurences table
