update cron jobs for updating meeting times

[kwhitehall]

The cron jobs are not behaving as expected. Updates to be made include:

• allowing only the dates on index.html and about.html (where the meeting times are found) to be updated. Currently the entire html repo is searched for updating, this can lead to changes of dates in the 'reminders' sections of the monthly meeting notes.

• the timing of when the jobs are to run. Currently they aren't running at the expected times thus leading to unexpected (& untimely) page updates
  The current settings are:
  0 0 15-21 * Sun meetingDate.sh
  0 0 8-14 * * monthlyReminder.sh
  0 0 * * Thu monthlyReminder.sh

• The cronjobs are very naive and change any date that meet the requirements. This poses an issue for times when the meeting date is changed around to accommodate events. More specifically, sometimes the events dates are changed (if they fall on the third Saturday) and other times the monthly meeting times are unchanged (if they don't fall on the 3rd Saturday).

These cronjobs are being suspended on the server until this issue is addressed.
