WebView 1.8:

1. possibility to open HTTPS sites via gate.aspero.pro (invisible for user), not working for files
2. rewrite parse tag function to fix broken URLs on page in some cases ("/user" instead of "/user/")
3. fix hand cursor appearance, fix progress bar on page load
4. load homepage on submitting empty url in adressbox
5. F12 - debug on, F11 - old tag parser on
6. unify page/file downloading code
