* Continue component library class clean up and encapsulation work.
* Change hierarchical sheet label container to boost::vector_ptr.
* Encapsulate hierarchical label handling in hierarchical sheet class.
* Convert some missed occurrences of wxString::GetData() to GetChars( wxString ).
* Fix some minor code formatting issues.
In netlist generation, changed the rule to calculate netnames of nets with labels:
Previously, named nets (i.e. nets with local, hierarchical or global labels) have their name
defined by the first label found in list.
So net names could be changed without really changing the schematic.
Now the names are calculated from the rules (by priority order) :
1 - use the most top level labels in hierarchies.
2 - use global labels first, local labels next (hidden power pins names are global labels).
3 - use alphabetic sort (so, if GND and AGND are connected, the net will be always named AGND,
and adding a VSS connection cannot change the net name)
So power nets and nets that have more than one label cannot have their netname changed
if there is no actual change relative to these nets names in schematic
* 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.
* EESchema: right click on ERC check mark displays error in message panel.
* 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)
* Replaced find dialog with wxFormBuilder version.
* New find dialog is modeless, supports more advanced search features,
remembers it's last position, size, search history, and search settings,
and implements initial support for replacing.
* Added Shift+F5 hot key to search for next DRC marker. F5 now just
repeats previous search.
* Minor cosmetic enhancements to label edit dialog.
* Remove tab from grid size text printf to fix toolbar grid combobox
display in wxGTK.
* Updated my TODO list items.
