algorithm (needed for the file selector and useful for other purposes, like assembling lists of livery or screenshot files etc.) - io.nas: move fixpath to string.nas (it's not only useful for file paths but can also be used for property paths) - screen.nas: move trim to string.nas (used by screen.nas and nasal-console.xml) - gui.nas: add pattern matching to FileSelctor - ufo.nas: use patterm matching (only *.ac and *.xml files shall be listed)
