CSV Injection in Camptix

Hello, Ian! I see you tried to escape "=, -, +, @" in your code ([#151516](https://hackerone.com/reports/151516)), but let me show simple workaround. I've made CSV injection by using this string ";=cmd|' /C calc'!A5" without doublequotes. ";" will bypass your trying to set the quote in the beginning of the string. ";" acts as a new cell separator. Tested in the Excel 2016
