Restructure qml files

[devendrn]

This PR updates the names of qml files to be more consistent. Trying to follow a "Window > Screen > Section > Component" hierarchy.

The reasons for each change are mentioned below:

ThemedControls/*.qml -> Components/*.qml
The directory includes not just themed controls but also some custom components.

Launcher.qml -> MainNavigation.qml or could be MainLayout.qml
Main front page. Shows screen as well as navigation bar.

LauncherMain.qml -> HomeScreen.qml
MinecraftNews.qml -> NewsScreen.qml
Mods.qml -> ModsScreen.qml
GameLogWindow.qml -> GameLogScreen.qml
LauncherSettingsWindow.qml -> SettingsScreen.qml
Screens that come under MainNavigation

LauncherBase.qml -> BaseScreen.qml
LauncherLogin.qml -> LoginScreen.qml
LauncherUnsupported.qml -> UnsupportedScreen.qml
LauncherChangeLog.qml -> ChangelogScreen.qml
LauncherUnlock.qml -> UnlockScreen.qml
"Launcher" seems unnecessary. Use "Screen" instead to give better context.

GampadTool.qml -> GamepadTool.qml
Small typo

EditProfileWindow.qml -> ProfileEditPopup.qml
No longer a window.

LauncherSettingsGeneral.qml -> SettingsGeneralSection.qml
LauncherSettingsStorage.qml -> SettingsStorageSection.qml
LauncherSettingsVersions.qml -> SettingsVersionsSection.qml
LauncherSettingsDev.qml -> SettingsDevSection.qml
LauncherSettingsAbout.qml -> SettingsAboutSection.qml
Use "Section" to imply that it comes under a screen.
