Manual on github.io related to application launch is partly non-operational

[Ricky Tigg]

Description: part of suggested commands are not in related to current material. On Linux Fedora 28, applies to files made available for download from http://unetbootin.github.io/linux_download.html.

Manual on github.io related to application launch is partly non-operational

Improvement suggestion: documentation to be updated. ('To run these binaries, (...) then start the application by running ./unetbootin-linux'.)

Actual results: command './unetbootin-linux' does not operate to start application; the following ones do:
'sudo QT_X11_NO_MITSHM=1 /home/user/unetbootin-linux_version_.bin', or
'su -c 'QT_X11_NO_MITSHM=1 /home/user/unetbootin-linux_version_.bin''.
