* Abstract out non-UI code to separate DLL
This change seems rather large, but it's mostly just moving anything that is not directly driving the UI to its own, separate library. This will make it easier at a later date for any UI improvements or changes as well as making the code much more discrete. One TODO has been added as a result of this change.
* Remove MessageBox from library
This change removes the last UI-driven elements from the library. This now makes the library (in theory) UI-agnostic and removes the TODO.
* Options is more UI-related
* Fix Nuget references in csproj
* Add Winforms UI
This is a clone of the current WPF UI but implemented in Windows Forms. WPF is not currently supported by Mono for Linux and macOS, so this can provide an alternative to those users who want to run on those systems instead. This also adds a second artifact for the Winforms build.
1) Fix the issue where custom parameters that include the `/s 2` flag crash the program
2) Make editing custom parameters a little more intutive (still need to figure out either a way in-documentation or in-UI to explain the checkbox a little better). This part of the change needs to be more tested but there aren't many people using the current feature anyway.
3) Fix the random "Error count: -1" issue that some users were seeing (ended up being a result of more things being in the `_mainError.txt` file than originally anticipated)
* Update DumpEnvironment.cs
Change Disk to Disc in printable strings of DumpEnvironment.cs
* Update OptionsWindow.xaml
Change Disk to Disc in printable strings of OptionsWindow.xaml
