[development] Install profiles should be in their own directories

Part of the confusion is that, grammatically, it should be "Installation 
profile."  (Nouns can be adjectives, and nouns can be verbed, but verbs 
can't be adjectives.)

Installation profile works for me, but I prefer package configuration or 
package description.  If the file will be *.profile, then package 
profile seems good.
