Merge pull request #294 in FS/freeswitch from ~NIMAST/freeswitch-fs-7549:feature/ladspa_stop_api to master 

* commit '4c5125b5d2c7d1b2a42131da1de419f4220a2f98':
  FS-7549 #resolve Added an API for removing an active ladspa effect on a channel. For conformance reasons, the uuid_ladspa command now accepts 'stop' and 'start', while the previous functionality (without any verb) which will simply add ladspa remains intact.
