Minor config/setup changes

[ghost]

Hey.

Got a few changes here, so I'll just make a small list:

• Remove setuptools from requirements. IIRC, it gets handled automatically.
• Use the newer recommended syntax for description files.
• distutils is deprecated, so switch to setuptools. This doesn't seem to break anything.
• setup.py changes the version number from 1.06 to 1.6; that seems undesirable. This doesn't happen if you make it 1.0.6.
• Load install requirements dynamically from requirements.txt. That way, you only have to keep track of one list.
• Move venv to proper XDG config directory. This should work if someone sets $XDG_CONFIG_HOME.
• Quote arguments in tordl.sh when passing them to python.

I'm also working on a bunch of other things, such as support for copying magnet links to the clipboard instead of opening them in a client, as well as some other major engines. I'll do PRs when I have the engines ready, but I don't want to flood you with random PRs otherwise. So, please feel free to take whatever you like from my repo's branches anytime. I don't care about getting credit or anything like that. I just do this for fun, and because I think this a great tool.

Cheers mate, cool news, thanks for caring. I'll rebase as soon as I'll have some time (soon). And ofc you deserve the credit, feel free to update licence file :) Iam planning to implement jsonrpc server mode together with using uvloop for performance, so this could be used as a core for a website, for example.

Have fun coding, x0r0x
