Add support to ignore certain diagnostics

[spahnke]

Adds the property diagnosticCodesToIgnore to the interface DiagnosticsOptions which allows users to ignore certain diagnostics. A prime example would be A 'return' statement can only be used within a function body. (1108) if the editor is used in scripting environments where the actual code is implicitly wrapped in a function.

Fixes microsoft/monaco-editor#1069
Fixes microsoft/monaco-editor#1452

Example

monaco.languages.typescript.typescriptDefaults.setDiagnosticsOptions({
    diagnosticCodesToIgnore: [/*top-level return*/ 1108]
});

Use indexOf to be compatible with IE 11

Super awesome!

I'm trying to find the list of diagnosticCodesToIgnore, but I'm a bit lost..

Does anybody spare have a link to spare for a lost programmer stranger? 😓

@hems This is written in the first comment in the PR:

monaco.languages.typescript.typescriptDefaults.setDiagnosticsOptions({ diagnosticCodesToIgnore: [1108] });

[spahnke]

I don't know if there's a designated list with all diagnostic codes, but the code is always shown with the diagnostic itself. In fact, this is how I found the code for the A 'return' statement can only be used within a function body. (1108) diagnostic.

Thanks @spahnke, that's exactly what I was trying to figure out!
