- remove need to use mysql for escaping the sql -- removing single quote
  should be enough
- instead of using sql to fetch categories from a live database, simply
  consider categories an integer range, specified to the size of that in the
  aur-schema.

Lukas: Add "CATEGORIES_COUNT" initialization. Fix random number range
used in genCategory() (AUTO_INCREMENT columns are 1-based by default,
not 0-based).
