* 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.

Added how-to-build-for-windows.txt with instructions how to build and install kicad from source under Windows using cmake.

* Change tabs to spaces.
* Make Boost required.
