Configurable paginator button labels (#229)

[nscarcella]

Hi,

I am working in a project in Spanish and the paginator buttons looked a bit out of place, so I added two props previousPageLabel and nextPageLabel in order to be able to pass a localized text to my table.

I didn't change the default 'Previous' and 'Next' texts as #229 suggested to avoid any backward compatibility issues (though I do think '<<' and '>>' are a nice, more international, alternative).

I manually only changed the following files:

• paginator.jsx
• table.jsx
• reactable_test.jsx

All other changes in the commit where caused by the build, which I guess was a bit out of sync because I see changes there that could not possible have any relation with my changes : P

Please let me know what you think and if there is anything else I can do to help.

Nice! thanks! Appreciate the concern for backwards compatibility.

[nscarcella]

Awesome! Thanks for answering so quickly!

I left another PR just in case that adds a line about this change to the README.(#262)

Do you have any idea when can I expect a version increment containing this change in npm?

as soon as the README PR is merged I'll bump a patch version
