Add Docs Placement tab to view CodeAfterInjection from previous documentation file as a reference when patching.

[mbedda]

• Add a "Docs Placement" tab in HookViewControl displaying CodeAfterInjection from docs.json
• Add DocsPath setting to UserSettings to persist the file location
• Prompt to locate docs.json on first hook view if undefined, with an option to skip

This is helpful when patching (atleast for me) to know where the intended placement is for a flagged hook.
