Change license to MPL 2.0

[peterbe]

We're currently using Apache License 2.0. We should be using MPL 2

[peterbe]

@leplatrem Do you know why it's Apache 2.0? And would it be hellish to change it now?

[mostlygeek]

Change it to MPL2. Pretty sure it won't affect anybody.

[leplatrem]

There was something annoying with MPL2 like having a header in every source file or something like that. Apache 2 was cool enough, never bothered

[peterbe]

That's not hard to add. I'll change it to MPL 2.

[leplatrem]

That's not hard to add

The headers? In each file, present and future? That's enough to avoid using a license IMO :)

[peterbe]

Yeah, it sucks but we've said we'll use MPL2. 78 files :)

Next step, add this to every file:

# -*- Mode: python; indent-tabs-mode: nil; tab-width: 40 -*-
# vim: set filetype=python:
