Falling back to regex solution for default value when value is malformed

Added the following tests which fail without the patch and pass with it:
    1) should fail gracefully when the default value has an unmatched bracket
    2) should fail gracefully when the default value has an unmatched quote

    Prevent filenames beginning with underscore

    A lot of related software (most notably github.io and the default configuration of jsdoc itself) ignores files with names that begin with an underscore, but the makeUniqueFilename() creates such filenames when the incoming filename is blank. This patch modifies makeUniqueFilename() to insert the ASCII letter "X" before empty filenames or filenames that begin with an underscore.
