Allow templates to be found in user .hgtemplates directory.

This little patch permits the user to put templates into a .hgtemplates folder
in their home directory. If the user does not have permission to write to the
system install directory for mercurial, they can drop their templates in here.

for example:

~/.hgtemplates
    map-cmdline.nlog

then, they can do something like this:

[alias]
nlog = log --style nlog
