opkg: various additions

	- only wrap package descriptions when outputting to a tty, simplifies parsing descriptions with external utils
	- introduce -i (--nocase) flag which makes all matching operations case insensitive
	- introduce "find" command which searches package names and descriptions (e.g. opkg -i find "*autoconfig*")
