[SPARK-13157] [SQL] Support any kind of input for SQL commands.

The ```SparkSqlLexer``` currently swallows characters which have not been defined in the grammar. This causes problems with SQL commands, such as: ```add jar file:///tmp/ab/TestUDTF.jar```. In this example the `````` is swallowed.

This PR adds an extra Lexer rule to handle such input, and makes a tiny modification to the ```ASTNode```.
