add HGRCPATH env var, list of places to look for hgrc files. if set, override default hgrc search path. if empty, only .hg/hgrc of current repo read. for each element, if directory, all entries in directory with end in ".rc" are added to path. else, element is added to path. big thing about this change is that user "~/.hgrc" and system hgrc not longer breaks tests. run-tests makes HGRCPATH empty now.

hgk "committer:" bug I've been having an hgk problem with this tree: http://xenbits.xensource.com/ext/linux-ppc-2.6.hg, specifically changeset 93c590d23a53. The problem seems to be that the commit message contains a "committer:" line, which triggers a (relatively unused?) case in hgk.py... Both cases need the dates at the end of the line.
