added support for beast1 trees

[brj1]

BEAST1 trees have a separate annotation ([] block) for edge statistics. I have added a simple gsub to move these edge statistic into the child node's [] block. Should be checked to make sure it doesn't break BEAST2 or MrBayes input.

[GuangchuangYu]

can you show me a sample file?

@GuangchuangYu good point. Should have included a sample file in the original comment. Below is a BEAST MCC tree with edge and node labels:
