Tidy up the output that comes from cmd's -help option by wrapping
at 78 characters, and picking the breaks sensibly. This changes:

Add the CMD_SINGLE_OR_FLAG option which permits a parameter to
either have a single value, or no value at all. If it has no value,
then it behaves in the same way as the current 'flag' implementation.

Add support for adding aliases for parameters, in the same way as we
can for syntaxes. This allows multiple different names for a single
option, as well as providing a way around problems with abbreviations.
Aliases may not be abbreviated.

Add a load of accessor functions to help with pulling values out
from the the cmd_syndesc structure. The idea here is to make it
simpler to manipulate command line values, as well as starting to
hide the structure of the cmd_syndesc structure from callers, with
a view to eventually making it private to the cmd library.

Rather than having to use cmd_Seek, followed by cmd_AddParam,
followed by another cmd_Seek, add a function which permits parameters
to be added at specific reference points. This allows programs to
declare a list (either as an enum or specific #defines) of parameter
code points, rather than using raw numbers.

Split up the command line parsing behaviour out of the cmd_Dispatch
function, and into a function of its own - cmd_Parse. This lets servers
which only have a single "syntax" installed just parse, without needing
to go through a dispatch function, and all of the control flow
complexity that requires.

Add some tests for the command library to the integrated test

to ensure that we don't break any of this functionality when modifying
the library.
