This fixes an issue where the game specific graphics backend would be saved as the global setting after playing a game.
This also now displays the currently running graphics backend when looking in the graphics configuration window.
The player getting a better view of their surroundings than the game would normally allow could possibly give the player an advantage over the original hardware, so Freelook is disabled in hardcore mode. To do this, I disable the config flag for Freelook when it is accessed, to make sure that it is disabled whether it was enabled before or after hardcore mode was enabled.
Memory patches would be an easy way to manipulate the memory needed to calculate achievement logic, so they must be disabled. Riivolution patches that do not affect memory are allowed, as they will be hashed with the game file.
This widget will be used in several places to notify the player that a feature has been disabled because hardcore mode is on. It includes a button to open the Achievement Settings so that Hardcore Mode may be turned off. Also included is the framework required to open AchievementsWindow specifically on the Settings tab.
This makes it so that if you just want to reload the current style (eg. on program start, or in response to a system event), you don't need to know the name of the currently selected user style. It's also more consistent with the way the 'userstyle/enabled' flag works.
GCAdapter::UseAdapter() reads s_is_adapter_wanted, which gets
initialized by config_guard.~ConfigChangeCallbackGuard(). So we must
wait until after destroying the config guard to know whether we have any
controllers set to GC Adapter.
1 ) When first opened, the (user selected) post process shader config widget would print the wrong values on the text label next to int range sliders. For example if the range was from 1 to 6, and the value loaded from the config was 1, the label would print 0 when first opened, to then start showing the correct value once the slider was first moved.
This mirrors the behaviour of the float slider code below:
```auto* const value_box = new QLineEdit(QString::asprintf("%f", m_config_option->m_float_values[i]));```
2 ) The defautl int slider value would also be set wrong on first load, as it was being divided by the slider max instead of the slider step amount (again, just like for the float implementation). This is a mistake I had made with my previous submission.
