Changes:
* Added EXTRA_COMPONENTS variable to build. Use it to automagically install files into the components dir.
* Added SYSINSTALL variable. Use it install files onto the system.
* Move mozilla-config generation from configure to makefiles
* mozilla-config will now generate paths based upon the MRE-based directory layout.
* Generate mozilla script from template
The installation heirarchy currently looks like:
$prefix -> /bin/mozilla
/bin/mozilla-config
/include/mozilla-ver/*
/lib/mozilla-ver (mozappdir)
/components
/res
/defaults
/chrome
There is preliminary build support for MRE dirs as well though the component manager hasn't had MRE support added yet.
$prefix -> /lib/mre/mre-ver (mredir)
/components
