* when Coati is started with no java-path or global cxx header or framework paths in the appsettings they are auto-detected using the first working detector
* order in which the detectors are shown in gui now matches the order they are added to the combined detector.
* implemented a dynamic way (that does not involve the linker) to load the Java runtime library
* implemented JavaPathDetectorLinux
* Filepicker for Java runtime library now asks to pick JVM library instead of folder
* extended error handling for JavaEnvironmentFactory
* implemented a more generic approach to detecting filepaths
* reimplemented standard header detection using this approach
* added auto detection of JVM dynamic library on windows
* fixed java tests that were broken when updating the java_indexer project before this commit.
* moved detection files to lib_gui
* added ui to global header search and framework search ui in project wizzard and preferences
* detecting the search paths will add them to the list if not added yet
* only detected compilers are shown in the dropdown list
