Various WSPR fixes

Make WSPRnet.org spot uploads tolerant  of network issues, spots still
get  discarded for  any period  that  has problems  but now  uploading
resumes on the next period.

Ensure that  decoded text starts  with correct  font by not  using the
base class append method directly.

Fixed a major  memory leak in the WSPRNet class  which was not freeing
processed request reply objects.

Added some helpful debug prints in WSPRnet.org spot processing.

Also  tidied  up a  number  of  class  implementations that  were  not
including he MOC generated code.
