[LAD] Some mudita24 fixes in SVN now.

[Tim E. Real]

Hello.
I noticed mudita24 SVN was in a sad state, crashing the whole system.

There were already significant changes and improvements since release 1.0.3
So I fixed 'er up. Please give it a spin so we can put out a release sometime.

mudita24 is the updated replacement of envy24control, the gui for 
 ice1712-based audio hardware.

subversion: svn checkout http://mudita24.googlecode.com/svn/trunk/mudita24
 mudita24-svn 

1) Moved to cmake build system. No more autotools   :)
    (The default install location is /usr/local. It can be changed -
      try the handy 'ccmake' gui).
2) Fixed wrong alsactl location. Now cmake looks for alsactl. 
   Override with environment variable ALSACTL_PROG. 
3) Added usage info. 
4) Fixed serious fatal X error: height too big. Was far too many markings, 
     brought down the system, due to lowest alsa db value now returning 
    -9999999. Installed some limits.   
5) Executable is now called mudita24 instead of envy24control.
    This should help kind packagers out there finally get this into the repos.

Cheers.   Tim.
