SConstruct: automatically update .hg/hgrc with style hooks.

Browse source 
Seems easier than pestering people about it.
Note also that path is now absolute, so you don't get errors
when invoking hg from subdirectories.
Also whacked unused mercurial_bin_not_found message (the
code that used this was deleted a couple months ago in
rev 5138d1e453f1).
