Support MacOS (#20)

Fix build issues to allow use with MacOS.

- Fix compiler warnings, type casting stuff.

- Require GNU sed. MacOS version silently produces wrong results as it doesn't support GNU escapes. NB. Can this be rewritten, perhaps with python script?

- Fix #include path issue. MacOS uses case-insensitive filenames and warns about conflict between "jerryscript.h" and "Jerryscript.h". Refactor to isolate jerryscript paths which aren't required by applications
