commit e2bd8dd0d5c2fc8ffab3135461093ae03f864c6d
Author: Marcin Kolny <marcin kolny flytronic pl>
Date:   Tue Oct 14 17:10:19 2014 +0200

    Gst::Context: wrapped GstContext struct
    
        * .gitignore: added generated files to ignored list.
        * MSVC_2010/gstreamermm/gstreamermm.vcxproj:
        * MSVC_2010/gstreamermm/gstreamermm.vcxproj.filters: added context
          files to a msvc project.
        * gstreamer/gstreamermm.h: added context header to a common include
          file.
        * gstreamer/src/context.ccg:
        * gstreamer/src/context.hg: added wrappers for GstContext structure.
        * gstreamer/src/filelist.am: added context wrapper to build file list.
        * tools/m4/convert_gst.m4: a few conversions between GstContext and
          Gst::Context added.
