#42 make email addresses configurable

[Adam Crews]

currently email addresses are hardcoded into scripts,
web pages, and possibly some binaries. All of these
places should reference a viariable, possbily from
lpenv, or psconfig.

Also start adding support for regionalized
email/support phone numbers.
