Update on Agenda Panel v0.2

- Bug fix on Calendar Panel: Before, initialization sometimes did not
highlight the correct week; now it does.
- Connected the .accdb reservation table with C# code
- Agenda Panel now shows the number of reservation per hours (on the
Agenda_Buttons)
- Agenda_Buttons foreground colour will change depending on the number
of reservations during that hour. for example, 40 and above is Blue, 25
and above is Green, and default is Gray.
