In most case the assignment to null was not necessary since it was easily provable that the (local) variable wouldn't have referenced after that anyway.

* Remove redundant command table entry from schematic editor.
* Remove unused variables to fix GCC 4.6 warnings.
* The usual Doxygen comment and coding style policy fixes.
* Encapsulate file name member of base screen object.
* Encapsulate associated screen member of schematic sheet object.
* Create add screen method to schematic sheet object to simplify setting
the associated screen.
* Move the change file name code in the schematic sheet object to the edit
sheet method in the schematic editor frame object to eliminate message
dialogs.
* Improve reference counting in schematic screen object.
* Add helper type definitions for changing schematic object storage to C++
containers.
* Fix a minor problem with wxFileDialog to open a file that no longer
exists in PCBNew.
* Make GerbView open file behavior the same as PCBNew.
* Remove redundant PCB file wild card definition.
* Add open file refactor task to the todo list.
* Fix some minor code formatting issues.
* Add CMake script to generate DSN token header and source file from
token list file.
* Add preliminary component library DSN token list and lexer file to
test script and prepare for new component library file lexer.

* Remove PCBNew header file dependency from common DSN lexer source.
* Minor code clean ups.
* Some bugs fixed
* Starting enhancements in Libedit: menubar and commands to "plot" current component in PNG or SVF file (SVG file not fully working, must be refined)
