Download and launcher failures (ext Windows 10)

There are many reports about launcher failure on windows 10 systems:
- can't run downloaded jar-file at all;
- jar-file opened as archived file;
- errors on downloading updates;
- errors on launch app;

If you have report or bugs with windows then post here. I will try to fix it on next releases.

Basic problems:
- [ ] can't run launcher without java installed on PC:
* need to add native windows app;
- [x] can't run game from wrong paths (like $):
* fixed $, but there are may be other issues like long paths;
- [ ] errors on access denied to folder or files (run from program files):
* need to replace all temp files creating from app folder (e.g. images folder -- the only one folder for write access needed);
* need to add environment compatibility report before launch (check installed software, access to folders, files exists);
- [ ] cmd-files out of date and do not work in some systems:
* need to place more cmd files or native tools for workaround;
- [x] xmage can't run under java 9:
* need to fix that;
