realvnc 4.6.0

the JpegQuality works great, I set it below 10, it is something like the tight encoding, and it seems more cpu friendly.

ctrl-space works now, no need to do anything prior pressing the key-combination, in ultravnc, I need to press scroll-lock first

I am using realvnc more now, before I am for ultravnc, I am using 2 vncs + rdp, I am so afraid that if one service crash, I will not able to make connection. haha
