Add more pk- functionality
Make pk-install output more informative on errors

I need to change it's structure though
Little refactirings of pk-*

1. Use pk-common for global constans
2. Quote $1 etc when needed
Make pk-install and pk-rm work for local dir
Test if backup path is reachable
Refactor pk install and rm scripts

Erase bad use of global variables
Add pk-unpack script
Make local var small case
Do not keep directory enties in list files again
Echo target dir in rm and install scripts
Add apt-cyg file to dotfiles
Add pk-sync command
Add update and find commands
Automatically remove all created tmp files
New pk-check and pk-setup, pk-update changed

New features of pk-update
1. Flat structure of packages
2. Refactoring
Use pk-make-dep-list2 in pk-common

Standalone file pk-make-dep-list deleted
Inform if there are no new files in pk-new
Changing struct of packages dir mainly

1. Move functions to pk-common instead of standalone files
2. Structureg of /build/packages is
	package/
		desc
		vers
		package-version.tar.bz2
instead of
	package-version.tar.bz2
	package-version.vers
	package-version.desc
Create deps versions file on pk-make
Leave only local installs
