pake task operation modes

[bergie]

we have basically 3 modes for midgard to run in

1. global (/etc/midgard/conf.d/), default MySQL db
2. user (~/.midgard/conf.d/), default sqlite db
3. self-contained (any dir, needs separate custom php.ini for each case), probably should not default (at least not silently) sqlite

the pake tasks should take these scenarios into account and have flags and/or heuristics to determine which case to use.

Flags is probably the right thing here. So the installer could either accept a --deployment-model parameter with values global, user and directory or ask it when installing.

does anyone really need "user" mode for mvc applications?

[rambo]

probably not for MVC apps, I'm not 100% sure though.
