Dropdown option for selecting the year

[hahmadia]

Hello!

When working with the calendar component, I realised that the year selection slider could at times be annoying. It was hard to select a year when the range of years was a lot and especially on small screen phones, it could be a pain to get the accurate date.

That is why I decided to add an optional prop for making the year selection either through a slider or a dropdown menu. Now you have the ability to select the year through the default slider or decide to use the dropdown instead.

Also, I experienced issues with sliding between months on android phone so I have temporarily disabled it in this pull request as well. (Related to issue #11). If someone fixes it, they can enable it again and make a pull request for that issue.

Hoping that my pull request can get approved and merged into master! Thank you!

This is what it looks on android before you have opened the dropdown. When you click on the highlighted blue box, then the modal open.

When the modal open, it looks like this:

This makes it a lot easier to select the dates.
