Summary: AGOS: Code analysis warnings

Initial Comment:
Here are the warnings I get when compiling the AGI engine using Code Analysis in VS2010.

I tried to remove all the obvious false positives. Some warnings look suspicious, others are pointing to correct code that still might benefit from better error checking.

d:\sources\scummvm\scummvm\engines\agos\script_pn.cpp(894): warning C6011: Dereferencing NULL pointer '_stackbase'
d:\sources\scummvm\scummvm\engines\agos\string.cpp(858): warning C6011: Dereferencing NULL pointer 'ptr' (looks like a false positive)
d:\sources\scummvm\scummvm\engines\agos\verb_pn.cpp(188): warning C6011: Dereferencing NULL pointer '_dragStore'

Note: If you want to try it yourself, you will need:
 - the create_project patch set, along with the WIP code analysis patch (http://bitbucket.org/Littleboy/scummvm-jt/src/942f13a9f24b )
 - the following patch to silence some false positives ( http://bitbucket.org/Littleboy/scummvm-jt/src/tip/COMMON%20-%20Add%20annotations%20for%20analysis%20build%20configuration.patch )
 - Visual Studio 2010 Ultimate or Team System (create_project support for analysis with VS2005/2008 isn't complete yet)
