Better ban rule failure messages & allows for additional custom messages

[ChrisMBarr]

This PR does 2 things.

---

1️⃣ Better Wording

The wording of the failure message for the ban rule (and the no-console rule since it is based on the ban rule) has been updated.

👎 Before

function invocation disallowed: object.someFunction

(The word "invocation" always reminded me of a wizard casting a spell... 🔮 )

👍 After

Calls to 'object.someFunction' are not allowed.

2️⃣ Optional Explanation Messages

Most TSLint rules are basically either turned on or off and they offer explanation text or it's generally understood why the rule is enabled in a project. One thing that's always bothered my and my teammates is when a function is banned it basically just says "this is banned" and it doesn't tell you why. Since I'm the one who turned on the linting rules I eventually get someone asking me "why can't I use _.filter? I can use in in this other project just fine..."

Well, now an optional 3rd parameter for each banned function call can be added. This text could offer an explanation as to why it's banned and/or offer an alternative that could be used instead of the banned call. Here's an example of how it would be configured

"ban": [
      true, 
      ["myApp", "someFunc", "'myApp.someFunc' has been deprecated, use 'myApp.otherFunc' instead"],
      ["_", "filter", "Use the native JavaScript 'myArray.filter' instead."],
      ["_", "forEach"] //no additional custom message here
]

And here's what the failure message would look like with the additional text appended 👏

Calls to '_.filter' are not allowed. Use the native JavaScript 'myArray.filter' instead.

We don't want both banned functions to be someObject and someFunction, can we change those terms for one of them?

[jkillian]

Looking good @ChrisMBarr! Two tiny changes above to make if you can, and can you merge master into this branch so it's mergeable?

[jkillian]

Looking good, can you merge master here? I can't merge this PR as there are merge conflicts right now
