Windows: Show more details for leaked memory

RegenerationDialog.cpp
galaxql.cpp
sqlqueryctrl.cpp

- Enable file and line number details for C++ operator new in the post
execution memory leak report when debugging on Windows.

wxWidgets enables by default automatic leak checking at program exit,
however it does not enable by default the file and line number details
for leaked memory allocated using the C++ operator new.
