ads2inspire v0.3.0, new --fill-missing command-line flag

The new --fill-missing flag will query for INSPIRE-like keys that were referenced in the LaTeX source, but missing from the .bib file, and fill them into the .bib file if found.

ads2inspire v0.2.0, filtering infrastructure and minor fixes

• New command-line argument --filter-type, current accepts values ads and all
• Ignore revtex-generated files <job>Notes.bib
• Minor documentation update

v0.1.1 - first beta version

Bump to version v0.1.1

v0.1.dev14 - first PyPI version

Everything basically works, but robustness could probably be improved.
