unlock and locking mechanism

[kdsayang]

hi,

There are 3 types of locking and unlocking....

A. By teachers
(i)   Lock selected activities (only times)
(ii)  Lock selected activities (only space)
(iii) Lock selected activities (time&space)

B. By students
(i)   Lock selected activities (only times)
(ii)  Lock selected activities (only space)
(iii) Lock selected activities (time&space)

C. By room
(i)   Lock selected activities (only times)
(ii)  Lock selected activities (only space)
(iii) Lock selected activities

Before this, there is no indicator that time, space and time&space have been locked/unlocked in the teachers/students/rooms time table. Unless user explore the time and space constrains in FET, they will see all the rules about the locking/unlock constraints

So, I suggest that coloring system to be use as an indicator so that it is easy for user to recognize and edit it (lock/unlock)

No locking (unlock) = no color
Lock selected activities (only times) = green
Lock selected activities (only space) = yellow
Lock selected activities (time&space) = red

Of course many useful interface improvements are possible, but I am not good at the interface. I prefer to concentrate on the algorithm. I'll add your proposal in the TODO.
