Allow multiple hashtags to start comments at the beginning of a line.

[Moderocky]

Description

Any number of hashtags can be used to begin a comment, if and only if they are at the beginning of a line.

All of the comments here are comments.

# hello comment 1
## hello comment 2
broadcast "ok ## hashtag"
broadcast "ok" # comment
###### comment
# ## comment

The following would not be a comment since it does not begin a line.

broadcast "hello" ## NOT A COMMENT

The JUnit test will need changing for this to work, I'll get around to that some time.

TP made an enhancement not too long ago where you didn't need to require double quotes in string expressions inside strings, maybe that could also be looked at here to allow single pound signs, this can be accomplished by not interrupting the string parse for a comment, and also detectable if the quotes isn't finished.
