localmodconfig: Document localmodconfig in README
Someone (over a year ago :-p) asked me to document localmodconfig in the README file in the source code. I thought it was a good idea but other things were more important and I simply forgot about it. Well, I stumbled on the email asking me about this and I'm sending it out now.

"make randconfig" Create a ./.config file by setting symbol

+ "make localmodconfig" Create a config based on current config and
+ loaded modules (lsmod). Disables any module

+ To create a localmodconfig for another machine,

+ "make localyesconfig" Similar to localmodconfig, except it will convert
