CMake and other minor improvements.

* Merged CMake 2.8.4 version of FindwxWidgets.cmake with local copy.
* Merged CMake 2.8.4 version of UsewxWidgets.cmake with local copy.
* Bump required version of CMake to 2.8.0.
* Delete commented out include from eeschema/protos.h that I forgot on my
  last commit.

 #
 # USAGE
-#  SET( wxWidgets_USE_LIBS  gl xml xrc ) # optionally: more than wx std libs
-#  FIND_PACKAGE(wxWidgets REQUIRED)
-#  INCLUDE( ${xWidgets_USE_FILE} )
-#  ... add your targets here, e.g. ADD_EXECUTABLE/ ADD_LIBRARY ...

+#  # Note that for MinGW users the order of libs is important!
+#  FIND_PACKAGE(wxWidgets REQUIRED net gl core base)
+#  INCLUDE(${wxWidgets_USE_FILE})
+#  # and for each of your dependant executable/library targets:
+#  TARGET_LINK_LIBRARIES(<YourTarget> ${wxWidgets_LIBRARIES})
 #
 # DEPRECATED
 #  LINK_LIBRARIES is not called in favor of adding dependencies per target.
