// SynEdit correctly detects UTF-8 files without BOM as well as ANSI files with Umlauts.
// (Previous versions could not detect UTF-8 files without BOM?!)
// - If BOM is existing, it will be removed. (which is good, because this is defined by PSR-1)
// Small things:
// - The scroll bars of SynEdit are not affected by the dark theme
// - dark theme full screen: doubleclick to desktop pixel "0,0" cannot be used to close the app
// Future ideas
// - code insight
// - verschiedene php versionen?
// - webbrowser1 nur laden, wenn man den tab anwaehlt?
// - doppelklick auf tab soll diesen schliessen
