Days selection fix when using RTL languages

[DorWeid]

When trying to select a range of days ( when in Months view ) and using a RTL language (such as Hebrew) you'll find it buggy. It'll select the opposite days when in the current row and will do some weird stuff when passing between rows. I could not find any open issues or pull requests regarding that matter, so I decided to do it myself. I also added some documentation to the code to help me better understand it while finding a solution (I can take it down if it's a problem).

TL;DR

• The problem: Wrong selection indexes when using RTL language.
• Ways to reproduce the bug: Use the i18n example. Edit cultures.js by adding the selectable prop. Run it and select ar-AE.

p.s
This is my first time creating a pull request.

thanks for the contribution! I'll take a look at the code, its a bit tough for me to see what's new with the comments but that's ok, just take me a bit longer to read through

hey there 👋 sorry for the delay, can you rebase this to fix the conflict?

[DorWeid]

Hey, I actually found a better solution than the current one, as it applies only to drag selection event, and not single cell selection. I will update soon.

Hey @jquense
Project should be OK now and is up to date with master branch.
Also removed documentation for your convenience :p
