pisi sandbox build - build with only base and devel

Usage:

# create your build dir and enter
$ mkdir build
$ cd build

# create your sandbox
$ pisi-sandbox create

# build whatever package you like
$ pisi-sandbox build http://svn.pardus.org.tr/pardus/2009/devel/network/analyzer/traceroute/pspec.xml

Currently tmpfs is using 1GB of ram... this can be decreased or increased or no tmpfs can be used but
disk can be used... but after build when tmpfs is unmounted, memory is the fastest to clean everything.
