populate employee_ids table
new input file format (new fields)

updated mapping details in comments
clean up
saving some work form last week

1. ITRPT report now has 'First Name' in the header so our header
detection is modified accordingly
2. instead of email we are using employee id for hash key
3. changed variable name $clear_data to $clear_table for clarity
4. one of the employee ids ends with the character 'a'. lisa knows
about this and did it to fix some issue. changed regexp to allow
for this special case.
including dn to store along with employee ids

employeeIds.pl creates the ldap.employee_ids table which contains
every user's email, dn, and employee id. this info is used in
sync.pl to determine employee's managers.
