Merge pull request #89 from phyloref/fix-specifier-authorities

This PR cleans up Regnum phylorefs in several ways:
* Renamed files from `REGNUM_*` to `CLADO_*` and increased the number of digits to seven.
* Moved Phylonym Phyx files and scripts out of the `encrypted/` directory so that they will no longer be encrypted (closes #82).
* Created subdirectories in `phyx/phylonym` for two kinds of errors we've been running into: `newick-problems` and `newick-recursion-error`.
* Added `phyx2owl.js`, a script to convert Phyx files to OWL for testing -- I'll replace this with the phyx.js library later.
* Added `phyxfix.js`, a script to correct errors in curated Phyx files on the fly, and used it to fix specifier authorities that were not loaded correctly (i.e. before PR #96).
* Incorporated some of the phylogenies prepared by Anna Becker.
* Removed two files with failing Newick strings and two test clade definitions from Regnum.
