Tidied iocli exports, build macro tweaks.
Removed 4 overloads of CCommandBase::RunCommand[L] that are no longer used at all, and changed one more to not be exported as it's only used internally to iocli.dll.
fixed builds on platforms that don't support btrace or any form of tracing.
A few words about how and why the tool-kit's UIDs are defined here.
The motivation for centrally defining all the tool-kit's UIDs in one place
was to allow them all to be changed into the non-protected range, thereby
allowing the tool-kit to be installed using a self-signed SIS file. Note,
self-signed SIS files can only be used with UIDs in the non-protected range.
Each platform that the tool-kit supports gets to decide which range of UIDs
it will use. The platforms (i.e. sub-directories of \fshell/platforms)
decide which range to use by whether they define FSHELL_PROTECTED_UIDS in their
platform.mmh. This macro is picked up by common.mmh (which is #included by
all .mmp files) and any .cpp or .rss (or similar) files that need it.
