More Linux-DOSemu ease of use-isms (cmdline specifier magic)

Support temp_dir (%g) and text_dir %(z) expansion to magic DOSemu drives/paths.
Use DOSemu-compatible temp_dir and text_dir paths in drop files.
Automatically recognize native node_dir paths in %f (e.g. editor temp files) and replace with DOSemu equivalent.
