Added support for the '~' symbol for home directory representation in database names in f_opendb in mged.c.
CAUTION: Works perfectly only on Linux and OSX. No Windows support.
Feature Request - https://sourceforge.net/tracker/?func=detail&aid=3202421&group_id=105292&atid=640805
An amendment to my previous statement: Issues known to exist on Windows, so Windows support has been disabled.
