capitalize.js has misspelled exports and imports

[PhilArtin]

The file capitalize.js may cause problems in some projects, because the imports, exports, and function names are misspelled. For instance, in utils/index.js the import is misspelled as "captialize" in both the module and path of the import.

The function in capitalize.js is misspelled, and input-range.js has it misspelled in the import. I was going to submit a pull request to fix this, because I thought it was just one file but then I found a few more places that need to be fixed and unfortunately that's a bit more than I can submit atm. But the list in this issue should have all of the needed fixes.
