* [Companion][LogsDialog] Use relative path for Google Earth track icon (fixes#5080); Use detached process to launch GE (does not restart GE for every export, does not keep handle to GE process); Fix typo in warning message.
* [LogsDialog] Use GE export file path as base for icon path (don't assume TempDir); Fix auto-connection warning from Qt due to misnamed function; Remove redundant check for existing GE file.
