Fixed chunkinfo and RAllocatorHelper crashes.
Details:
* Tidied leak docs
* Updated dialog command to workaround text windowserver bug and implement DIALOG_IMPL as an enum option. Also tried to support dismissing the dialog with CTRL-C but ended up just printing a warning as the notifier API is broken
* Fixed RAllocatorHelper::OpenChunkHeap() (and thus chunkinfo <address>) and took Adrian's latest changes.
* Fixed chunkinfo OOM problem
SPCRE
Currently, it is mostly a direct port of Google's C++ wrapper
around PCRE for Symbian so there is still quite a bit lacking.
* Add Locale support
* Support more PCRE options in TRegExArg
* Refactor to use more templates and less macros in TRegExArg.
* Full UCS2 support and not just UTF8. Unfortunately, this may slow things down
as PCRE doesn't support this natively so some wastefull conversion will have
to take place.
* Port unit tests over to TEF. Will get rid of lots of code duplication.
* Include CRadix parsing
