here goes:
1. corrected float parsing to allow also ".XXXX" (no number before .) per Lidia correction
2. corrected errors in merging/copying empty pages per lidia correction
3. added source groups to the cmake build files, so now everything is nicely arranged
4. fixed regular Xcode projects iOS targets: missing base SDK for simulator, and free type prefix header issues per Benjamin suggestion
5. changed NO_TIFF -> PDFHUMMUS_NO_TIFF and NO_DCT -> PDFHUMMUS_NO_DCT, per Max suggestion
pc syncs to recent changes
