[Codelite-developers] wxDateTime::Parsex functions

During compile, I would receive warnings such as
"warning: converting to non-pointer type ‘long int’ from NULL 
[-Wconversion-null]"
pointing to the files

sdk/wxsqlite3/src/wxsqlite3.cpp
sdk/databaselayer/src/dblayer/SqliteResultSet.cpp

The documentation for wx294 shows 
wxDateTime::Parse[Format|DateTime|Date] now returns a boolean ( was 
wxChar* of failed character).

Patch to update wxDateTime::ParseX usage.
