Some PEP8 tidying and moving from -f filter1 -f filter2 to -f filter1,filter2
More tidying as tiles are always square.
Correctly check for problems with the tile image.
Update README.md
Update README.md
Added a setup.py and moved around the folder structure.
Delete tyled.py
Why is setuptools so hard to use...?
Update README.md
Fixed a ratio bug as well as adding brightness control.
Update README.md
Removed the error when a tile doesn't fit exactly- a warning is better.

Also added a contributing.md
I have changed how effects are applied. They are no in the format tyled.py -e foo:1:2:3, bar:3:4:5
Update README.md
Split up the code, simplified logging and made it so that a count for each filter can be specified.
I have shifted pattern logic to a new file, with a new argument -p / --pattern
I have moved to allowing the user to enter multiple tile files. I just need to rethink make_grid to accommodate this.

Next, I can generate tiles from xcolours.
I have added support for generating tiles from .Xresources, colours passed along from the command line as well as setting the size of generated tiles.

I need to add more patterns now.
I have added grid, vstripe and hstripe layouts.
Some PEP8 tweaks and more input error handling.
