* More exit tweaking to make shutdown faster

* Fixed active upload icon in Web UI
* Fixed text alignment in Web UI preferences dialog
* Fixes to ratio display in Web UI transfer list and properties panel
* Edited Queued/Paused/Checking icons so that they are the same for complete/incomplete torrents (easier to understand)
* Color torrents in UI transfer list as in qBittorrent < 2.0 (more easily understandable)
* Progress and size are now updated when files are filtered in torrent properties
