Automatically suggest adding/removing remap=true on mixin-related annotations

[JBYoshi]

Could you add a warning for mixin annotations when the remap value of an annotation doesn't match the obfuscation state of the target?

Relevant annotations I've found:
@Mixin
@Accessor
@Invoker
@Shadow
@ModifyConstant
@Inject
@ModifyVariable
@At
@ModifyArg
@ModifyArgs
@Redirect

This will also be added to @Overwrite in the future: SpongePowered/Mixin#179 (comment)

remap = true is the default.

This should be specific for targetting non-obfuscated targets, without remap = false.

@DenWav From SpongePowered/Mixin#551, annotations may still require an explicit remap=true in some cases even though it is the default.

A good first step for this would be to suppress the "default annotation value" warning and quick fix for the remap field, since it can be misleading. Then, we could work on re-adding an inspection explicitly for the remap that is aware of the unconventional context-sensitive behavior.
