    Remove redundant try-catch around OnModuleBuilding invocation

    If this exception is going to be rethrown, there's no reason to include
    a try-catch.

    Include the ModuleBuilder in OnModuleBuilding

    This allows modules hooking into OnModuleBuilding method to mutate
    theirselves at runtime.

    Rename method to more intuitive 'OnModuleBuilding'

commit 9a166ef1d0
Author: Joe4evr <jii.geugten@gmail.com>
Date:   Mon Jan 15 19:09:10 2018 +0100

    Add callback method for when a module class has been added to the CommandService.

* Add request info to HttpException & RateLimitedException (#957)

* Add request info to RateLimitedException

* Remove Promise from interface.

* Add Request to HttpException.

* Incorrect variable assignment (#959)

The username parameter was being used to set args.AvatarUrl as opposed to the actual avatarUrl parameter provided

* [docs] Change 'Echos' to 'Echoes' (#964)

* Don't attempt to load types with generic parameters as a module

This fixes an issue where custom ModuleBases that contained a generic
parameter would be loaded as a module - only to fail when trying to be
built.

Realistically, ModuleBases _should_ be abstract - but it was still a bug
that we allowed them to be included as a module.

* Correct impl. of HasFlag and ResolveChannel (#966)

HasFlag was checking if any of the flags were set, not the ones
specified, and ResolveChannel was still treating the ChannelPermission
enum as before it was changed to a bitflag.

* Add more tests for Permissions class (#967)

* Add tests for more Permissions code coverage

* Add guild tests

* Add more in-depth covering of permissions methods

* Add tests for OverwritePermissions

* Remove unknown ItemGroup tag from csproj

* Add missing Fact attributes, separate class so that it is not dependant on main test fixture

* Separate out GuildPermissions and ChannelPermissions tests from main partial Tests class because they do not need to have access to the main test fixture

* AddModuleAsync/AddModulesAsync should not require an IServiceProvider

If one is not passed, they will default to an EmptyServiceProvider

This resolves issues where since the merging of OnModuleBuilding, users
were effectively forced to use the DI pattern, where before they were
not.

While this isn't necessarily a bad idea, we shouldn't just change this
behavior for no reason (though I assume making the IServiceProvider
argument required was a mistake)

* Allow nested ModuleBase classes to be built when declared from non-module classes. (#969)

* Allow modules to be built regardless of their declaring type.

* Need to exclude submodules.

* Add Missing Parameter For WebSocket4Net Constructor (#968)

* Add missing param to constructor

This should fix `15:02:44 Gateway     System.MissingMethodException: Method not found: 'Void WebSocket4Net.WebSocket..ctor(System.String, System.String, System.Collections.Generic.List`1<System.Collections.Generic.KeyValuePair`2<System.String,System.String>>, System.Collections.Generic.List`1<System.Collections.Generic.KeyValuePair`2<System.String,System.String>>, System.String, System.String, WebSocket4Net.WebSocketVersion, System.Net.EndPoint)'.`

* Bump WS4N to latest stable
