Enhancement: Complete drop-in replacement

[UInt2048]

As of v0.0.8 alpha, CyberKit was released with renamed frameworks, such as:

• CyberScriptCore.framework (replaces JavaScriptCore)
• CyberCore.framework (replaces WebCore)
• CyberKitLegacy.framework (replaces WebKitLegacy)
• CyberKit.framework (replaces WebKit)
• libwebrtc.dylib (replaces libwebrtc)
• libANGLE-shared.dylib (replaces libANGLE-shared)
• libswiftCyberKit.dylib (replaces libswiftWebKit)

Due to the renaming, the symbols in libswiftCyberKit are not a drop-in replacement for WebKit's (since the symbols depend on the name of CyberKit.framework / WebKit.framework).

CyberKit intended to end the renaming, but was met with a crash log like the following.

A null pointer dereference such as shown here in the CoreFoundation method _CFGetNonObjCTypeID is the result of a bundle identifier mismatch between the bundle identifier used in the CFBundleRef (typically created via CFBundleGetBundleWithIdentifier) and the actual value of the bundle identifier.

In upstream WebKit and in CyberKit, target bundle identifiers are set via configuration files, which should be revisited in the event of this type of crash.

I think it cant be that "drop-in replacement" for now, because we are unable just to bindmount it on top of /System/Library/Frameworks/WebKit.framework and others...

If only we could do that - we could fix ALL issues with web pages on all jailbreak-supported devices!
That will pretty easy to use but it is not that hard to implement i think...
