FactoryJoe recently asked me about theming the pager. Looking at the
code, I decided it was way too much uncommented voodoo. So here's the
cleanup patch.


The biggest change is that before this patch, the pager would count
items. When there are 5 items per page, the urls would go from=0,
from=5, from=10, etc. The code also handled in between values, e.g.
from=2 or from=13. IMO this 'in between' feature is useless (you can
only use it by typing in the url yourself, and once you do the pager
remembers the in-page offset) and it complicates the code.


Instead of this, I made the pager count page numbers. 'from' is simply
an integer per pager: 0, 1, 2, 3... This makes the code simpler. I also
commented it some more, and cleaned up some inconsistencies in the code.
Finally, the code had a lot of (int) casts in it. Most of these were
unnecessary as the variable was either the result of a calculation, or
used in a calculation. I got rid of those that had no effect.


Functionally, nothing changes except the meaning of "from" in the pager
URLs. I hardly think anyone would link to a specific pager page.
