Current Behavior

Mod+right-mouse button click resizes windows

Desired Behavior

I use xinput to remap my middle and right click mouse buttons because I find having selection paste on a proper button more useful that clicking my scroll wheel. To allow i3 resizing to work with this I wrote a patch to make the middle mouse button have the same behaviour as the right mouse button:

This addressed my issue, but might be better solved by allowing mouse button behaviour to be configurable.

I have run the test suite over my patch and it passed. Just checking if I can submit a pull request, or if I should make some more changes before doing doing so.
