[Dev] CPIA borders

[Jed Burgess]

Donn asked me to look at CPIA's use of borders and in doing so I 
realized we were completely ignoring any borders specified in 
parcel.xml.  I just checked in a change so that we now set whatever 
borders you specify in parcel.xml.  There is one caveat, and that is 
that currently wxWidgets limits what we can do with borders.  Right now, 
you must either specify 4 matching borders (2.0, 2.0, 2.0, 2.0) or only 
specify one border and leave the rest as zero (0.0, 0.0, 2.0, 0.0).  
This is a limitation that we plan to fix, but haven't done so yet.

One consequence of finally paying attention to borders is that the look 
of Chandler changed substantially (people had specified borders all over 
the place even though they weren't being used).  I did my best to make a 
pass over cleaning up the look, but it's in a lot of places and 
sometimes it was unclear whether whomever had set the border wanted the 
look they had or whether they wanted the border they had specified.  If 
anything looks odd (too much border, not enough) this is likely the 
culprit, but an easy fix.

Let me know if you have any questions/problems,
