[Feature] Check if admin/require admin

[nopeless]

Prevents users from accidentally invoking script without administrative privileges

That's possible to add, but main idea is that users will use exe file, and it requests admin privileges anyway.

I have added this check and auto-elevation code into latest version of PS1 script, but cause app migrated to C# and exe distribution it doesn't play any role anymore :)
