add getter for component "name" property
stop tracking gitattributes, headache!
component "aname" property no longer needs to be gettable
add getter for component "hname" property
add getter for component "type" property
fixed gravatar feature extension registration, wrong name (slug)
moved scheme class to ICE/base/ dir
dropped "base_theme" property from scheme class, redundant
always begin scheme loading with the active theme
added two file loading helpers for safely scoped include/require statements
global configuration settings are now set with helper functions
