[sc-dev] quarks install actions

[stefan kersten <sk@xxxxxxxxxx>]

i'm wondering how and when to perform certain actions (building,
cleanup, etc.) when installing quarks.

maybe we could add an actions field with callback functions to the quark:

(
...,
actions: (
	preInstall: {
	},
	postInstall: {
	},
	preUninstall: {
	},
	postUninstall: {
	},
	...
)
)

thoughts?
