Streamulus license changed to Apache 2.0

Following a request from a potential commercial user, Streamulus is now distributed under the Apache 2.0 license.

I initially selected the Gnu license because I like the copyleft spirit - you take, you give back, everybody wins. However, I realize that it is probably not a practical license in today's world.

Under the Apache 2.0 license, you can use streamulus with few restrictions, as long as you give credit where it is due (i.e., leave the copyright notices where they are) and clearly identify the changes you make.

I enjoyed working on streamulus and enjoy it even more when it is used. If you find it useful or interesting, please find the time to drop me an email and let me know a bit about how you got interested in streamulus and what your use case is.
