Add the ability to optionally hide the operating system label in the UI

[icnocop]

DotNetInstaller should have the option to hide the operating system label in the UI to potentially support new operating systems when they are released without having to make any code changes for example.

See conversation here.

You can do this in the htmlinstaller in index.html. Comment the following out.

<div id="os" />

Thank you, Adam!

When using the MFC-based bootstrapper, there's still no equivalent way to do it yet.

In this thread: https://github.com/dotnetinstaller/dotnetinstaller/issues/90 p4bl0cs said:

The only workaround I've found was to change the label's position (dialog_osinfo_position) to a negative one (i.e. -1000, -1000) or set the width and height to 1 (thankfully no pixel whatsoever is shown).

I haven't verified this works perfectly myself but it's worth a try until a proper fix is released.
