Tree imports fail with trailing comment

[shawnlaffan]

( First reported on the mailing list: https://groups.google.com/forum/#!topic/biodiverse-users/kvjTV7PLRtI )

Attempts to import trees in newick format with trailing comments fail.

The error is coming from the tabular tree import method, which is the final fallback method if the nexus and newick methods fail.

The workaround for now is to delete the trailing comment.

Example tree:

((((('2500000:1500000':0.333333333333333,'2500000:500000':0.333333333333333):0.172619047619048,'3500000:500000':0.505952380952381):0.273102521758436,('3500000:1500000':0.379310344827586,'3500000:2500000':0.379310344827586):0.39974455788323):0.13761176395585,'1500000:1500000':0.916666666666667):0.0156084656084655,'3500000:3500000':0.932275132275132):0[trailing comment]

This will actually affect any comment block that does not use json-like formatting.
