[WIP] Add Startup Warning for Systems with Secure Boot Enabled

[robotman40]

As per this issue, many users face confusion after installing third-party drivers and facing an inoperable or partially function Linux Mint experience.

The problem here often lies in secure boot preventing drivers from loading, so in order to guide users on the right track if they run into problems, I added a warning dialogue box.

I am very new to open-source and this is one of my first few contributions ever, so if I did anything wrong, please be blunt about it. I really want to be a good contributor.

As for all the 5 commits listed, it was me struggling with Git on PyCharm, so please forgive that.

First off, thanks for tackling this.
As for the warning message, it should probably inform users that self-signing the modules is an option instead of suggesting that disabling Secure Boot is the only option. Personally, I think Secure Boot is poorly done, even if well-intentioned, and I don't use it on my personal systems which only have Linux. But I think most people want to be using it, especially if they're dual-booting with Windows.

I added your suggestion to the dialog box. Let me know what you think and if there's anything else I could possibly do.

I think this is a good idea, but I also think it's too verbose and not shown the right way. Instead of a dialog which gets in the way of opening the tool the user required and which has every change of being dismissed without being read, this could be a simple warning message in an infobar above the drivers list.

Another thing to consider.. secureboot isn't an easy concept to grasp and it's not easy to configure. This message is way too advanced for casual users. They're better off just being given a layman terms warning "Warning: Secure boot is enabled - some drivers might not work properly" which pushes them towards google or forums discussions, than being told about documentation they don't have and signing they might not understand.

@clefebvre: I agree with all that except I would add "until signed" to the end of "Warning: Secure Boot is enabled - some drivers might not work properly"

If you just tell people some drivers might not work properly, they might wonder if they can use them at all, or conclude that disabling Secure Boot is the only remedy.
