Add edit menu and right-click menu items to pcbnew for resetting module and other text field sizes to current defaults set in Preferences->Dimensions->Texts and Drawings.

* Move schematic select block from global variable to SCH_EDIT_FRAME.
* Remove redundant schematic drawing code for eeredraw.cpp.
* Move block select code into SCH_SCREEN object.
* Simpilify block item select code.
* Fix bug in SCH_LINE selection state test.
* Add test to schematic objects for connectability.
* Make copy block items function a private method in SCH_EDIT_FRAME.

* Schematic reference object now completely encapsulated.
* Schematic reference list object refactoring complete.
* Make OK default button in PCBNew block operation dialog.

* More schematic reference list object refactoring.
* Initial encapsultation of schematic reference object.
* Improve schematic reference object doxygen comments.
* Remove redundant library component lookup when generating net list.
* Fix doxygen waring in LIB_PIN object.

Pcbnew: Bug fix: arcs in modules outlines (when flipped) were incorrectly saved and read  in .brd files.
this was due to incorrect macro NORMALIZE_ANGLE (was the same as NORMALIZE_ANGLE_POS), now modified and renamed NORMALIZE_ANGLE_360

Fix a minor warning when starting Kicad in debug mode (wxWidgets 2.9.1 specific)

  * Added the basic structure to the Sweet parser in sch_part.cpp.
  * Got inheritence working off of the 'extends' keyword and PART::inherit()
  * Tossed the units support out of sweet.keywords, since we agreed to go dimensionless.
++richio:
  * Added the problemInputLine support to PARSE_ERROR, so UI can show the
    offending line of bytes.  Yes bytes, not even guaranteed to be characters.

Eeschema: cleaning code. Start work to enhance annotation algorithm.
Already added an option to annotate using sheet number (sheet 1 uses numbers 100 to 199, sheet 2 uses 200 to 299..).
Works fine if deleting existing annotation, but needs work to be used when the existing annotation is kept .

  * Deleted kicad_exceptions, because it required the big #include <wx/wx.h> and
    that was slowing down compiling.  Moved that stuff back into richio.h where
    it came from.
  * Enhanced IO_ERROR to format an errorText.
  * Added THROW_IO_ERROR() and THROW_PARSE_ERROR() macros to capture the
    the call site of the thrower.  If you have problems compiling, it is probably
    due to the definition of __LOC__ in richio.h.  Some compilers may not support
    __func__ in C++ yet.  Find a macro that identifies your compiler, and we can
    work out something in the #define of __LOC__.

to PART::Parse() from test program.  Ready now to complete the PART parsing.

Include image file inline on main HTML page.
Added HTTP_LIB_SOURCE.
Added utf8.h

    Completed most of /new class LIB_TABLE.
    Completed all of /new class LPID.
