This is in preparation for adding a new deob module which invokes the
bytecode deobfuscator, decompiler and AST deobfuscator in turn.

Some static members are not scrambled in the client. Maintaining a
one-to-one mapping between instanced and static classes makes
refactoring easier in these cases.
The browser control filter is removed as we now get the same
functionality for free.

This already caught some cases of public members that should have been
private and one case where the inferred type was too specific.

This allows two different classes in different modules to be refactored
to the same name - for example, Node in client and unpackclass.
Under the hood, it is implemented by prefixing each class name with the
library name and an exclamation mark (which is highly unlikely to appear
in a class name, as it is invalid Java syntax).
At first, prefixing class names with the library name feels like a bit
of a hack. However, it is much simpler than trying to track libraries
throughout the existing code. Furthermore, it allows us to avoid
forking ASM classes like Remapper.
The Fernflower driver was also changed to deobfuscate each library in
its own context, rather than trying to decompile them all in one go - by
the time classes reach Fernflower, the prefixes have already been
removed and Fernflower can't deal with duplicate class names either.

I suspect it is excluded on Jagex's end so the client deals correctly
with any class loading failures caused by the absence of the
netscape.javascript.JSObject class.

This commit adds support for mapping:
* class names
* field names
* field owners
* method names
* method owners
It does not yet support argument names, local variable names or
re-ordering method arguments. Local variable names are blocked on
Fernflower patches and method argument re-ordering is blocked on the IR.
