2. No more image libraries in lib folder. Instead those files are taken directly from the libtiff-ios folder, where they are built.
3. No more leptonica & tesseract libraries in the lib folder of the repository. Instead those binaries are built automatically directly when run button in xCode is pressed
4. No more build_dependencies script. Makefile instead to build Tesseract and all dependent libraries.
5. An extra build phase has been added to the Tesseract OCR iOS framework. This phase simply runs the Makefile and build all the dependencies if necessary.
6. Readme files have been updated to mention above changes.

2. Removed internal tesseract and leptonica headers from the project.

2. Image fat libs are copied in ./libs and their headers in ./include

…ependent libs have been downloaded yet.

…o `$(arch)/lib` folder. So the lipo combines the multi architectural archive from those installed libs, instead of those intermediate .a files everywhere in the tesseract subfolders. As the result the size of the libtesseract.a is back to 21,5 MB instead of more than 62 MB.

2. 'lib/libtesseract_all.a' has been removed with the original official name of the Tesseract library, which is libtesseract.a
3. `Libtiff-ios` update till the version with `Makefile`
4. Remove redundant code from out Makefile, since #3
5. Remove `README_tesseract.md` since it's outdated.
6. Added ashton and his `libtiff-ios` reference and contributions to `README.md` in the used libraries section.
7. Also changed `README_how_to_compile_libraries.ms` a bit, since make is not as a rebuild step of the Tesseract-OCR framework anymore.

…S environment variable only.

2. Makefile updated to support ARCHS environment variable only for building specified architectures only.
3. README_howto_compile_libraries.md updated to explain above changes.
4. Prebuilt script changed to build only active architectures of dependent libraries in Travis CI build environment.
