[beeswax] Query editor does not properly split statements

Query editor does not take comments into account while splitting statements at semicolons. Also orphaned semicolons produce empty queries rather than being ignored completely. Following query will fail:

– This is a comment;
select * from <table_name> limit 100

Also the following query executes without the limit operator:
select * from <table_name> – This is a comment;
limit 100

The following query causes a parse exception because of an empty query in the beginning:

;
select * from <table_name> limit 100
