Merge remote-tracking branch 'TanYewWei/issue-16'

* Fix trailing whitespace
Set nowarn_deprecated_type erl_opt for R17 compat

R17 deprecates built-in type spec for dict() in favor of
dict:dict(). However, the latter is not available in R16 and below and
is a compile time error. Ignoring the warning isn't great, but allows
the code to compile clean on R16 and R17.

Also updating the list of supported/tested Erlang versions in the travis
yaml.
Better way of handling deprecations
Add older versions of erlang back in, we have to remove 17.0rc1 because it handles depcrecations different than 17.0, which makes life difficult
