* 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.

* PCBNew remembers last net list read during the current editing session
  as well as between project editing sessions.  Closes bug 576902.
* Separate PCBNew application settings from project file settings and
  allocate them dynamically instead of statically to make it easier to
  eliminate global variables.

Pcbnew: Fixed minor problems (bugs 568357 and 568356). Changed French word COTATION to DIMENSION in class COTATION (now class DIMENSION)

* 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.

Fixed a bug in search function in Eeschema: search for a component reference in a complex hierarchy was broken

Pcbnew: Fixed an issue in GERBER file creation, under Vista and W7 only for non administrator users
Plot files were 0 byte length.
This was due to use of function tmpfile() in a GERBER function to create a temporary file that seems not working using mingw.
Replaced by more usual files functions.

fixed very minor bugs.

Build BOM: in one part per line, fields are now selectable (like others formats)

* 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.

Updated denis dupeyron email address

  * DSNLEXER now owns an abstract LINE_READER by pointer so that polymorphism
    can be used in alternative LINE_READERS.
  * Write FILE_LINE_READER and STRING_LINE_READER.  The latter can be used
    to parse text coming from the clipboard or other string source.

This paves the way for other kinds of LINE_READERs, such as one which reads from a
multiline string which comes from the clipboard. 

Will still need to:
1) add new additional DSN_LEXER constructor,
2) virtualize the LINE_READER's ReadLine() function
3) create derived class from LINE_READER.

This patch applies on the very last svn  (r2402) and removes all
disfunctionnal python code (including deletion of unused strings)

* Make USE_WX_ZOOM clipping routine actually clip rather than just test
  if line needs drawn.
* Clean up as many USE_WX_ZOOM #ifdefs as possible.
* Minor coordinate rounding improvements.
* Minor scrolling and panning improvements.
* Remove unused KicadGraphicContext object code.

    1)  nested quotes.  This is in anticipation of broader usage of the
        file type/syntax.  A string like this in the file:
            "my ""favorate"" string"
        can be returned as
            my "favorite" string
    2)  CommentsAsTokens is implemented, so you can ask the lexer to return
        comments as tokens, so they can be preserved.  The default is to ignore
        them.  A comment is defined as any line that has # as its first
        non-blank character.  (This means comments cannot follow anything else
        on a line.)
