Issue #52 - Fix FileStructure.MultiCueNoNewlineBetweenCues

Test now expects to parse successfully, expects to parse 2 cues, and
expects a WEBVTT_EXPECTED_EOL on line 5 column 1 (beginning of line
with unexpected '-->'
Correct whitespace

Added space between ',' and 'true' on line 313
Inserted missing comma (filestructure_unittest.cpp:315)

Added comma between WEBVTT_EXPECTED_EOL and '5'
Merge pull request #55 from caitp/issue-52

FileStructure.MultiCueNoNewlineBetweenCues should parse successfully and return 2 cues
