replace libdparse in style guidelines visitor

[lucica28]

Look at function/variable/class names to respect the style guidelines. Example of problematic code:

module AMODULE; // [warn]: Module/package name 'AMODULE' does not match style guidelines.
class cat {} // [warn]: Class name 'cat' does not match style guidelines.
interface puma {} // [warn]: Interface name 'puma' does not match style guidelines.
struct dog {} // [warn]: Struct name 'dog' does not match style guidelines.
enum racoon { a } // [warn]: Enum name 'racoon' does not match style guidelines.

Also changed the declaration of the analyzeDmd method to have a reference to the ModuleDeclaration so we can check declarations like module x;
