[UI][UDF] can create udfs with reserved words as names

In the UI udf tab it allows you to create functions using reserved words as names, even tho running the create function query itself doesnt allow this, and you cannot run the udf since it throws a reserved word error. Perhaps we should throw up a warning that it is a reserved word? or maybe in the UI tab we should show the function names with backticks? Right now it shows up as the reserved word alone, and if you try using it without backticks it won't work.
