traits v0.4.0

NEW FEATURES

• New package author: Chris Black (@infotroph) (#106)
• betydb functions now can do pagination (#94)
• betydb functions gain progress parameter to optionally suppress the progress bar (#113)
• EOL Traitbank completely changed their query interface - function no longer works as it did before. for now, you have to specify your own query that's rather complex, see docs for help. Later on we can try to simplify queries for users (#112)

MINOR IMPROVEMENTS

• table in README for different sources and clarify what traits are (#110) (#111)
• fixed link to Birdlife (#108)

• fix to ncbi_byid(): ten new fields added to the output (#101) (#102) thanks @boopsboops
