Patch to show the --opts in lvu

[Christian Riggenbach]

Hi folks

I have written a small patch for lvu, which enables the program to show
the given options (lin --opts) for modules. It extends "lvu info" with a
new line "Options:" and introduces the new command "lvu options".

I think it is necessary to enable an user to display this data, because it
can have huge affects on the compiled modules (and the value is kept over
to new builds).
