Some tweaks on walkbys stuff.

The normal (Maxis) way is 4 walkbys/day, at 10, 14, 16, 18 o'clock, plus some other checks about neighborhood type, presence of children, friends, and so on.

Now, I wanted more and more walkbys/day, random with no known/unknown modificators.

This hack changes the walkbys parade's timing from a fixed-hours-base to a range-base. 
I addeed a BCON with this new values, so the original one - which contains many others - remains identical. Addeed also labels, both for this new BCON and for original one, for better understanding of values.

* marhis-walkbys-nocheckonknown.package is my base: walkbys every hour, from 9 to 22, plus "sim known" check disabled.

* marhis-walkbys-vers1.package is walkbys every hour, from 9 to 22, only.
* marhis-walkbys-vers2.package is walkbys every hour, from 10 to 18 (Maxis range).
* marhis-walkbys-vers3.package is walkbys every hour, from 14 to 21 (afternoon only).
* marhis-walkbys-none.package for hermits: no walkbys at all, nope, never, let me alone.


It's very easy, in any case, to change range values in SimPE, if preferred.

Use only one of these at once.
