Subject: ASM Based Class Translator (#1)

* Initial port to ASM

* Package updates

* Annotation + inner class translation

* Fix inner class mapping

* More bytecode translation

* Signature refactoring

* Fix highlighting of mapped names

* Fix parameter name offset

* Fix anonymous class generation

* Fix issues with inner class signature transformation

* Fix bridged method detection

* Fix compile issues

* Resolve all failed tests

* Apply deobfuscated name to transformed classes

* Fix class signatures not being translated

* Fix frame array type translation

* Fix frame array type translation

* Fix array translation in method calls

* Fix method reference and bridge detection

* Fix handling of null deobf mappings

* Parameter translation in interfaces

* Fix enum parameter index offset

* Fix parsed local variable indexing

* Fix stackoverflow on rebuilding method names

* Ignore invalid decompiled variable indices

* basic source jar

* Output directly to file on source export

* Make decompile parallel

* fix incorrect super calls

* Use previous save state to delete old mapping files

* Fix old mappings not properly being removed

* Fix old mappings not properly being removed

* make isMethodProvider public

(cherry picked from commit ebad6a9)

* speed up Deobfuscator's getSources by using a single TranslatingTypeloader and caching the ClassLoaderTypeloader

* ignore .idea project folders

* move SynchronizedTypeLoader to a non-inner

* fix signature remap of inners for now

* index & resolve method/field references for usages view

* Allow reader/writer subclasses to provide the underlying file operations

* fix giving obf classes a name not removing them from the panel

* buffer the ParsedJar class entry inputstream, allow use with a jarinputstream

* make CachingClasspathTypeLoader public

* make CachingClasspathTypeLoader public

* support enum switches with obfuscated SwitchMaps
