cotvnc: update to chicken 2.2b2

[ryandesign (Ryan Carsten Schmidt)]

The cotvnc web site says it has been superseded by a new fork called chicken:

​https://sourceforge.net/projects/chicken/

It might be good to update the cotvnc port to chicken version 2.2b2. chicken 2.2b2 is old, from 2011, but it's newer than cotvnc 2.0b4 which is from 2006.

Normally if a project changes names, we would rename the port (as when osxvnc changed its name to vineserver). However, we already have a port called chicken for an unrelated software package. So we could either continue to call the port cotvnc, or pick something new like chickenvnc.

I was looking at this but I cannot find the proper distname to download. Any ideas?

[ryandesign (Ryan Carsten Schmidt)]

I looked at it too yesterday, and I couldn't find a source code distfile, only a dmg of a precompiled binary. We'd have to use fetch.type svn to download the source code from the Subversion repository.

Yes, that will work. I also wanted to make a -devel sub-port with a newer branch anyway.

r154026. Devel subport left commented out because it would not build for me. Hopefully someone else can take a look at it and get it fixed. The latest trunk seems stable and allows secure VNC.
