2.2.2

• Fixed FileUpload to support mulit-part form data uploads
• Added "OFFICE" to phone type enums to prevent errors when doing a GET on contacts for the Demo Company. - This enum value is not a valid phone type when performing a PUT or POST.
• Changed where the "Content-Type" header is set. Previously, it was set in the XeroHttpContext class on the httpclient, but this caused error for multipart-formdata. Setting the Content-Type header on the HttpPost or HttpPut objects solved the problem.
• Completed example calls for all Files and Folder endpoints in example/RequestResourceServlet class
• Refined the Files API Models using the OAS
• Fixed date issue with BankFeed Unit Tests
• Merged PR #111
• Addressed some ENUM issues from issue #112
