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.
To update the icon files:
1) Edit the .sgv file useing an editor such as Inkscape. Note, things like text
must be converted using "Path | Object to path" if they are to survive the next
step.
2) Convert the .sgv file to a Tiny SGV file using Nokia's SGV2SGVT tool (available in
the S60 SDK).
3) Convert the Tiny SGV file to a .mif file using "mifconv" as follows:
\epoc32\tools\mifconv fshell_local.mif /x /c32 fshell_local.tiny.svg
Note, it is important that the .mif file is not encoded in binary XML (the "/x"
option arranges for this) because not all S60 handsets can handle the more compact
format.
