- Update the project numbering system by also adding a sort field (defaults to

the project number field if blank).
- Add a new number option 'X', which counts among ALL projects, not just the
  ones in the same division/cat.
- Add a padding argument to N or X  (N0...N9) defaults to 2 for N, and 3 for X.
- Adds 3 columns to the project table:
	- projectsort: for storing the expanded text
	- projectnumber_seq: for storing the N or X number for projects
	- projectsort_seq: for storing the N or X number for the sort order
- Add a new config option for sorting, and expand the text for the
  projectnumber.
- Change the default sorting for reports and project lists to use the
  projectsort category.
- Remove the gvrsf_tn option from the database, it's not needed now.
