Add Apache 2.0 license

[Matt Bishop]

LGPL makes it impossible for most commercial products to use trove. I know, it shouldn't really, but ignorance being what it is, if you want more adoption of Trove, please add the Apache 2.0 license to your list of licenses.

[Rob Eden]

Personally I'd love to allow this, but there are prior contributors and copyright holders that won't allow a license change (or addition) to Apache (and really anything other than LGPL).

Sorry. We may try to remove "encumbered" code sometime in the future, but it will be a big job.

[Rob Eden]

And just to re-iterate for the record: as you already stated, LGPL is completely compatible with commercial usage.

[Matt Bishop]

I understand. Do you have a list of code paths that are encumbered?

[Rob Eden]

No, that's a lot of the hard part. It's the original contributor, so it's all mingled in with the development done before 2.0. Likely it will be a rewrite of most things.
