* crash when creating a sheet that does not yet have a sch file
* when loading schematic file v 1 annotations are applied to all sheets independent of path in hierarchy
* component reference is drawn by default upon placing a new libary comp. 

counterparts, will be connected together if they have the same label (name) and are on the same sheet. 

  Added item "Delete" in "Edit" menu.
  Added menu "Place" with all possible 
elements from the right toolbar.

* made schematic loading of 'GLabels' dependent on the schematic file version (currently at 2). 
If the version == 1, these are loaded as hierarchal labels
* made text labels global in the herarchy, consistent with their historical usage.

        * commiting my changes to allow multiple instances of a given schematic file within 
a hierarchy:
        ** internally, m_currentScreen has been replaced with m_currentSheet,
                which is a list or 'path' of screens.  The path of screens is used to 
generate
                a series of timestamps, which is converted to flat component reference via 
a look-up
                table in the schematic files.
        ** this means that m_currentScreen is no longer used -- use GetScreen().
        ** GetScreen is virtual, as some of the dialogs keep around a WinEDA_BaseScreen 
pointer.
        ** all sub-sheets in a given schematic must have different names to generate a 
meaningful netlist.

Russian translation update.

* Change tabs to spaces.
* Make Boost required.

This allows you to install only specific components (i.e. binaries, resources, doc files in specific languages), particularly useful for package mainatiners.
Default install will work as before (i.e. install everything).

* fixed a bug in hierarchal shematics where a loop (e.g. same file included at different points in the 
hierarchy)  would cause infinite memory use.   
* added a edit footprint hotkey to eeschema, since it seems I'm always editing '0603' '0402' etc. on the 
common components, and it was difficult to edit this information before.

solved drc.cpp error (pcbnew crashes in track creation or edition). very minor other changes (translation)
