[Users] free-TLS released in experimental tree

[Cesc]

Hi,

This is a notification that the first release of free-TLS for SER has
been commited to the experimental tree in the CVS repository for SER.
For openSER it will be (i think) committed to the core CVS repository
right away.

User testing is required to fast-track it into the main core, so I
encourage you to give it a try. More will be added soon to ease
testing (for example, test certificates ready to use ... but you can
also create your own).

It contains a README file, which should be enough to get things
started. It will be improved with a fully working tls_only.ser.cfg
file in no time. Also more developer help will be added in the README,
for people who want to collaborate.

This is all for now.

Regards,

Cesc
