core/server.py:  Made a few minor changes to the early log_file_prefix detection to better handle first-run situations.  Also added some better error messages for the situation where the set uid/gid don't exist.
gateone.js:  Modified `GateOne.Utils.showElements()` and `GateOne.Utils.hideElements()` to work more like their singular counterparts (using classList and whatnot).
terminal_input.js:  Wrapped the logic that unhides the pastearea after copy operations in a 50ms timeout to workaround what appears to be a bug in Chrome on macs.  It's short enough that no one should ever notice.
