Hello..

Very nice job man!
I think I want to start hacking on lp95 to try out a few ideas.

Here is a start for some config files to make it easier to work with for people using [flake8](https://pypi.python.org/pypi/flake8)-based tools. I've just set it to allow tabs for indentation since you use that, I've also added another file to tell emacs that tabs is the thing.

It is much easier to read consistently formatted code, especially when it comes to spacing rules.. 
How would you feel about if I fix most of the following things and make a pull request?
You seem to like tabs so let's keep them! If you have any 

````

53      E251 unexpected spaces around keyword / parameter equals
41      E261 at least two spaces before inline comment
37      E262 inline comment should start with '# '
234     E265 block comment should start with '# '
4       E271 multiple spaces after keyword
10      E272 multiple spaces before keyword
20      E302 expected 2 blank lines, found 1
77      E303 too many blank lines (2)
268     E501 line too long (83 > 79 characters)
2       E703 statement ends with a semicolon
372     E711 comparison to None should be 'if cond is not None:'
1       E712 comparison to True should be 'if cond is True:' or 'if cond:'
54      F401 'Live' imported but unused
17      F403 'from _Framework.ButtonElement import *' used; unable to detect undefined names

5863    W191 indentation contains tabs
122     W291 trailing whitespace
4       W292 no newline at end of file
462     W293 blank line contains whitespace
5       W391 blank line at end of file

````
Any of these rules can be disabled individually but some of them are quite helpful:

Especially warnings about mixed tabs and spaces since those can lead to real bugs
