Work around variable naming clash between CGI, JavaScript and PHP code. This made the content of timesheet_period revert to 1 on onChange().

Woraround problem where hours worked from other periods where accounted in this period. Now all hours worked are recalculated iso using the 'stored/cached' values that were created at timesheet creation time.

Read configuration from file and use it in addedit.php to determine if current user has "Timesheet approval rights". If it does, then allow setting "Approved" for this user.

Ran dos2unix for consistent end of line markers and bumped up the patch level of the version number to 1.0.1.

Implemented access control for users that are not allowed to delete timesheets when created. It is now assumed that only the admin will assign delete rights for people that need them. Be carefull the users filter box is also hooked up on this access rights. Once granted delete rights a user can delete timesheets from someone else.

This should be fixed in future. Currently I do not know how to fix this.

Added user selection to vw_idx_inc.php. This makes it possible to view the timesheets of other people besides those of yourself. This feature is not restricted to the admin.

- restricted timesheet_project and timesheets overview to current user only
- stored timesheet project details when status > 0 (is status submitted=1 and approved=2)
- fixed changing of timesheet_status and timesheet_period on 'new timesheet' action
- fixed addedit.php to display the right timesheet status even when status > 0.
- reworked addedit.php to put more code in functions. It uses showproject() or showtimesheetproject() function to print timesheet_project details.

Todo:
- introduce admin mode in which the admin can alter timesheets even when (status>0) and let admin see other peoples timesheet.

Removed code duplication by introducing a timesheets() php function that will be called from every timesheet overview type (status: all=-1, open=0, submitted=2, approved=3).

- Changing status and period of timesheet doesn't create 2 timesheet now. It only creates one timesheet or updates the current timesheet.

Feature added:
- Added a new row timesheet_worked to database for keeping a total of hours worked that timesheet_period.
- Added row timesheet_worked to inteface.

Make delete, changing status and period work. Make status and period fields in addedit.php readonly when the timesheet has been submitted and approved.

TODO:
- delete from vw_idx_*.php files doesn't work.
- changing status and period on new file creates a duplicate record.

TODO:
- deleting
- updating
- admin mode
- adding project hours and total to timesheet
