fixed erroneous meta file generation script
added ability for preset_hub to write/read presets or entire scenes from files. Improved documentation to reflect new additions and to improve existing.
fixed accelerated displace bug where nested structs did not get properly tagged/selected
added example files for the expanded preset_hub documentation
fixed segfault when closing array window/subpatch due to lack of checking of valid resize/move hook pointers
Fixed bug http://sourceforge.net/tracker/index.php?func=detail&aid=2457992&group_id=55736&atid=478070; hopefully also fixed incorrectly reported hit/selection boxes for nested structs (like the one reported in the previous bug report)
