This patch update bioinspired opencl code to make it working
with latest opencv, major changes include:

1. data structure update, e.g. oclMat to UMat.
2. opencl kernel optimization to get it running faster

Add MSLIC (Manifold SLIC)

* Support getTextSize() to resolve issue #927

This getTextSize() funtion helps to print more text,
either on the same line or on another line.
To add getTextSize() function, some member variables are removed
which are corresponding at putText() function's arguments.
And a negative fontHeight must be asserted.

* Fix to remove whitespace

Bug in Text module when set Optimization Level to "-Ofast" in xcode (#921)

* Bug in Text module when set Optimization Level to "-Ofast" in xcode

Bug when set Optimization Level to "-Ofast" (Fastest, Aggressive Optimizations) in xcode, read the wrong patch_size parameters to 7 (should be 8). This bug will occured in loadOCRHMMClassifierCNN function called by example_text_character_recognition and example_text_segmented_word_recognition.
