Minor language corrections in the tutorial document

Fix unsequenced modifications (Bug #3179).

Renamed ocl tests' precomp files according to convention.

Also, added the missing include guard to perf_precomp.hpp.
This should fix the build.

Made it so that a dummy .cpp is actually created when compiling with VC++.

Deleted almost all of the precomp.cpp files.

Looks like we don't actually use them; when creating precompiled headers
with Visual C++, a dummy .cpp is created at build time.

Removed extra {} in erosion and dilation functions

Removed obsolete CMake workaround.

Removed CMakeParseArguments.cmake, which we don't use.

It's part of CMake nowadays, too.

Removed OpenCVFindPkgConfig.cmake, since it's bundled with CMake now.

In fact, I don't think we actually use it... but I kept the include,
just in case.

Dropped OpenCVConfig.cmake - we don't use it anymore.

Removed CMake version checks that we don't need anymore.

Bumped minimal CMake version to 2.8.7.
