Subject: new data type flext::AtomListStatic using pre-allocated space if
 possible fixes for OSX replaced memory-intensive STL maps by custom-made
 vector/map-container fix for gcc strangeness no more static assignment of
 symbols (problems with Metrowerks) small fix for gcc fixed bugs in SIMD code
 for non-power-of-2 lengths fixes for attribute editor (to deal with large
 dialogs)
