merge_to control

[GoogleCodeExporter]

Users should be able to set multiple input PDFs to be part of a single
layer.  ie: merge rivers and lakes to produce a hydrology layer, with a
single checkbox and set of rules.

merge_to=  Accepts another layer's name.  Case sensitive, accepts white
space in name.

* We should allow chained merge_to statements
eg:   
name=A|merge_to=C
name=B
name=C|merge_to=B

* How should the program deal with loops?  Merge none?
eg:
name=A|merge_to=C
name=B|merge_to=A
name=C|merge_to=B.

this is now handled with the group= variable, which is set to some name and 
appears
as such on the panel. all layers that have the same group name will be 
combined. all
attributes are still supported
