Ideally we should probably split this bug up.  And also we have to deal with deprecation of we are changing functionality.  We may just need to change the docs and leave the bad names (and deprecate them).

git commit: 8ca9e3b4c48c328d226c56ec748bd0a52649c9fa

deprecated: (APIs still exist, but docs define as deprecated)
- system.listBaseChannels
- system.listChildChannels

new: (code basically moved from the deprecated methods above)
- system.listSubscribableBaseChannels
- system.listSubscribableChildChannels

note:
- channel.software.listSystemChannels - left alone for now
- for getting the current subscribed channels the following APIs currently exist;
  therefore, no changes made at this time:
  - system.getSubscribedBaseChannel
  - system.listSubscribedChildChannels
