Ignore media content with .nomedia in parent

Currently there is no quick way to ignore certain media files, the
android ecosystem has a '.nomedia' file to exclude directories from
being scanned. Add the same functionality to XBMC.

SlingboxLib: Fix alternative CSlingbox constructor

CSlingbox::CSlingbox(const char * szAddress, unsigned int uiPort /* = 5001 */) {
  // Call default constructor
  CSlingbox();
  ...
}

"CSlingbox();" - object is created and immediately removed.
Therefore with CSlingbox(const char * szAddress, unsigned int uiPort /* = 5001 */) class members will not be initialized.
