quickly corrected the previous refactoring of features2d: moved from set(SOME_PROP, val) to setSomeProp(val)

This and several following commits contain the "boring" changes required
to support the new Ptr. These are changes like:

* new T -> makePtr<T> or .reset(new T) or Ptr<T>(new T)
  (depending on the situation)
* p.empty() -> !p
* delete_obj -> DefaultDeleter::operator()

and similar changes that are numerous, but primitive.

All tests passed!

Made all STL usages explicit to be able automatically find all usages of
particular class or function.

Made changes to work in cv::Algorithm with parameters of these types.
Also fixed SimpleBlobDetector -- now it can be created by
cv::Algorithm::create and it can work with cv::Algorithm::set/get.

* typo in Algorithm::addParam for 'short' data type which results in segmentation fault on ARM
  on attempt to set type property for FAST using setter inherited from Algorithm
* added short type support to read/write methods
* improved some error messages

made it to give more verbose errors when arguments of wrong types are passed, added setters with types (e.g. setInt, etc)

This reverts commit a8c5e356.

lot's of changes; nonfree & photo modules added; SIFT & SURF -> nonfree module; Inpainting -> photo; refactored features2d (ORB is still failing tests), optimized brute-force matcher and made it non-template.

added the abstract cv::Algorithm class; low-level exp & fastAtan etc. functions for more efficient SIFT implementation; fixed bug #1521
