Adds support for querying packages

[bhavishyagopesh]

• Makes a system call to a import.sh script that finds the distro than does the import if possible and if not than everything occurs normally...
• Tested for archlinux but if you like the implementation than I could do testing for other distros too...and also add support for may-be open-suse.
• There is a possibility of a feature that you could revert, even, from the installation prompt(but that I don't think would be of much practical value as...how many valid python scripts match package names?)
• So views...

This looks good. I'll try to put it to test in a few days.
