[development] 4.8/5.0: Modules, the install system, and directories

I fully support the notion that every module has its own directory.

I have the following on my list when HEAD is open for features again.

We discussed it on the mailing list before, and an .ini file will have
the module name and description. This avoids the need to load all
module when the admin goes to admin/modules, and overcomes
the memory issue associated with that.

It also opens the door to putting in things like version number (not
file version, but release version, date of change, and many other
meta data, and nifty things).

Split mode is nice performance wise, but would it be overkill in most
cases?
