Added capability to parse out pandoc title blocks and use them for meta information.
Check that meta values are not empty before applying them.
Changed method for string compilation from JSON array. Now it handles symbols correctly instead of surrounding them with spaces as if they were an extra word.
Added handling to the new open2 process to make sure it terminated
Fixed bug that kept the author from being properly stored and used the quotemeta() function on the final meta values before passing them to pagestate so that special characters will also work.
Removed quotemeta() function. It didn't solve the problem and added visible escape characters to the HTML title. For now, if you want to surrount your title with quotation marks, you will have to put backslashes in front of them.
added error handling to avoid error message about uninitialized value in concatenation
