Update regressionfiles.txt with May A's file (Issue #123)
ORCA: fix for TD calc if symmetry isn't specified

* Create etsecs, etenergies, and etsyms if etenergies doesn't exist.
  Previously, these were only created if SINGLETS was in the TD-DFT/TDA
  EXCITED header.

* Be more explicit about etsyms: Singlet, Triplet, or Not specified
Gaussian: refactor and relocate parsing of gbasis (see cclib/cclib#110)
Gaussian: add support for gfprint keyword when parsing gbasis (see cclib/cclib#110)
Gaussian: minor fix for Python3 (cclib/cclib#110)
Gaussian09: merge Basis logfile into SP logfile and move old files to regressions (#110)
Gaussian: sort files in regressionfiles.txt
Gaussian09: update remaining unit test logfiles to revD.01 (old version moved to regressions)
Merge pull request #124 from ATenderholt/regressions

Handle ORCA TD singlets-only calculation
Regressions: add logfile from #116
Q-Chem: parse higher-order moments, but not properly for >= 10.
Q-Chem: Important fix for all jobs that run via OpenMP.

I'm not perfectly pleased that this involves removing an assert, but
considering that most real-world jobs are run with OpenMP threads...
Q-Chem: the non-specific MPn section was tripped up on a SOS-CIS(D0) job

The Moller-Plesset and coupled cluster sections will benefit from a
very specific, explicit (line-slicing) rewrite.

Q-Chem: Fix for all OpenMP jobs
Scan tests: skip tests if optdone is a bool
Gaussian: make more use of the Symbolic Z-matrix section
Regressions:: a bit of a hack for Gaussian09/BH3_fragment_guess.pop_minimal.log (closes #116)
