Updated ats_specialise_test_drop.pl to insert FileStoreAction param

Added new postAction to smoketest.xml

Restored signifcance of the MS tools not being available, as this only occurs when running a configuration that would try to use them.

Re-indented target "sf-os-compile" (following best guess as to the standard) to make it easier to read.

Re-assessed some of the raptor error messages to reflect the inconsequential nature of missing the MS dev tools when not trying to build the tools target.

Changed mergeXML.pl to use a better version of the XML printing algorithm, so it can generate well-formed content if the input includes some rogue &s or <>s.

If any files are in both the list of SDK headers, and the list of RnD headers, then they're only zipped in the binaries_epoc_additional zip, and not the binaries_epoc_sdk zip.

Fixed format checking of summary.csv to deal with new field.

Test: Add MediaMgmt smoke tests (not being built or run ATM)

Test: Remove the media management smoke test for now

Re-instated call to process raptor logs for BRAG purposes.

Remove s60 postfix from sf-s60-create-cenrep for Symbian^3

Fixed format checking of summary file so that it actually checks something!

Updated framework for packaging SDK headers so the contents to zip can be set by a project property (or it can zip everything together if it's not set).

add media mgmt to smoketest build
