Version 1.45

NEW (feature) : You can now choose which downloader to use, “Curl” (default) or the “Internal” downloader; using the “Internal” downloader could help if you're behind a proxy;

NEW (feature) : added proxy support to BootCaT (only with Curl downloader for now);

BUGFIX: corrected a bug that made BootCaT wait forever while trying to determine remote file size even when connection failed;
