Implementation of ?++ command for users with Admin Roles (Core, Maintainer, and Admin)

[timothyling1994]

1.Describe the changes made:
-Added regex to detect '?++' command
-Verified that the user is able to use '?++' command by checking their roles, only admin, maintainer, or core roles are able to use this command.
-Bot outputs appropriate message if user is not an admin/core/maintainer user
-If user does have an admin role, the API request to the award Points API is populated with an argument of 2 to award 2 points
-Resolved UnhandledPromiseRejectionWarning: DiscordAPIError: Cannot send an empty message that was being caused in some use cases because we were passing empty Promises in points.js to botEngine.js. We would then try to message.channel.send that empty response, causing the warning above.
-Added test cases in points.test.js for the ?++ command

@twalton83 Removed .DS_Store and botCommands/.DS_Store

You need to be sure that you're on the branch that has your features and add those files :) I accidentally closed the last PR, so be sure to include your changes.

@twalton83 To clarify, the issue is that this current PR is only showing the latest commit "removed DS store" and not the previous commits I made?

When I do 'git status' locally, I get:

Your branch is up to date with 'origin/main'.

I can confirm that my local main branch and my remote repo main branch (which should be tracked by this PR?) have all my changes. Can you point me in the right direction on the next steps?

I found this StackOverflow post that might be relevant: https://stackoverflow.com/questions/35407770/github-changes-ignored-after-revert-git-cherrypick-git-rebase/35408117#35408117

Are you on Discord? The fix is going to be a bit involved and it will be easier to communicate in real time.
