Remove SQLiteLib framework
Remove SQLiteLib from Products and Targets of Vienna.xcodeproj
Remove sqlite3 framework, we will utilise the system dylib in future
Add FMDatabase, from https://github.com/ccgus/fmdb/tree/fd95c38478849804c26abf93641013f47aa77f4e
Cleanup some extra FMDatabase requirements (although we don't plan to use FMDatabasePool, include's are cleaner this way)
Adopt FMDatabase and FMResultSet
Replace remaining SQLDatabase calls with FMDatabase sqlDatabase calls
Resolve Xcode warnings on releasing objects; fixup pointer memory handling of executeUpdate...() return values
Remove extraneous release calls to FMResultSet
Resolve Xcode warning of comparison between pointer and BOOL
Objective-C ARC is playing up in odd ways, disable FMDatabase's conditional setting of autorelease
Resolve a data sanitation attribute of FMDatabase. Looks to be working now
Various LLVM compiler suggested fixes
Update Acknowledgements to reflect FMDatabase library under MIT licence, thanks August Gus Mueller
