[PATCH 3/4] Make number of columns in stat overview configurable

[plenz at cis.fu-berlin.de (Julius Plenz)]

I'm pretty sure this constitutes a violation of how the data structure
cgit_period's use was intended, but that's much easier than passing the
"count" parameter to all the functions that need it.
