Bump the version number to 0.7.7.
Bump the version number to 0.7.7.

Changes since 0.7.6:
- add tags and uids from DICOM 2016b
- automatically include SpecificCharacterSet in all queries, because without
  it, decoding of non-ASCII text values cannot be correctly done
- if dicomtocsv has repeated "-k" attribs, e.g. "-k Key=Value", then do
  not override the earlier value if the later is "-k Key" with no value
- add "-u" option to provide a uid list file for dicompull

Bug fixes since 0.7.6:
- Add 94 missing characters to KS X 1001 and JIS X 0208 tables (Korean
  and Japanese), the files used for these were incomplete
- Crash in dicomtocsv if multiple enhanced multi-frame files in series.
