Please merge "requires" logic

[rovo89]

Hi, I have added something to the official installer to prevent situations where people are still using an old installer and wonder why the framework doesn't work properly. Basically, xposed.prop can now contain lines like requires:fbe_aware=1, which signals to the installer that it needs to support the fbe_aware feature. The installer has a list of features it supports, and as long as all required features are supported by the installer, all is fine. Otherwise, it won't allow installing the ZIP and will show a "known issue" warning if the user managed to install the ZIP anyway. This will ask the user to update.

I know that you have your own update reminders, but please merge this anyway: https://github.com/rovo89/XposedInstaller/commit/ffa1e3afabffeeeda3861a52d79d483462d47e82 https://github.com/rovo89/XposedInstaller/commit/b3afd0b87c6afab068c42f7b17d69ae4d977f820 https://github.com/rovo89/XposedInstaller/commit/ff695eba7f5347700bec5f7dd0961c3e59d789ad https://github.com/rovo89/XposedInstaller/commit/8a50348713c3cd5a25cd0db5aedc939308a6524b https://github.com/rovo89/XposedInstaller/commit/4b87be3147a6a387c39ccde81514db7becb74c57 https://github.com/rovo89/XposedInstaller/commit/5e9d4346840e7a4f0b5f9a2e8293743c002097dc

Feel free to adjust it to your own needs. The only thing that would be required (by a new check in XposedBridge) is that there is a resource string called installer_needs_update. Otherwise, the framework would show a Toast message.

Just added another commit to take the app name from the existing string resource: https://github.com/rovo89/XposedInstaller/commit/5e9d4346840e7a4f0b5f9a2e8293743c002097dc
