Fixed lots of issues with installing a low-caps version of fshell from SIS file. * Fixed issue in CCommandFactory whereby some APIs like GetCommandInfoL could trigger allocations on the wrong heap or signals to the wrong thread. The symptoms were often seen as a crash in the which_00 thread when running ciftest. * Lots of build fixes for when FSHELL_PROTECTED_UIDS isn't defined and when all capabilities aren't available. * Added new platform.mmh macro FSHELL_OPEN_SIGNED. * Open signing of fshell SIS files is now supported for production S60 handsets. Build fshell with the FSHELL_OPEN_SIGNED macro defined (and without defining FSHELL_CAP_ALL or FSHELL_PROTECTED_UIDS) in your platform.mmh and submit \epoc32\fshell\fshell.unsigned.sis to https://www.symbiansigned.com/app/page/public/openSignedOnline.do . The following commands are not available when using Open Signing due to Platform Security restrictions: fdb; kerninfo; chunkinfo; svrinfo; objinfo; sudo; fsck; localdrive; ramdefrag; readmem; reboot; setcritical; setpriority. Others such as chkdeps, e32header, ps, and fshell itself will run but in a restricted capacity (for example, fshell will no longer allow you to modify files in the \sys\bin directory). * Removed commands objinfo, svrinfo, chunkinfo, readmem, fsck completely when memory access isn't present - previously they would still appear in the help but would give an error if you tried to run them.
