cmake conversion #1

I've added a man page taken from your Debian building system.

I worked on the following parts:

Building using CMake on Debian required to add includes to UI files.
Next I have solved ascii cast.
Then I noticed that icons for application specific actions were not installed in the share/apps/kvpnc/icons folder but in common share/icons.
Finally, I added CMakeL10n and updated the translation template. It should be noted that some strings for translation in the application are totally insane. However, I have left this now unchanged.

For example: "%1:%2:%3", "%5: %2@%1, %3 [%4]", "%4: %2@%1, %3".
