Static mentions fix

Static mentions would still have '' when posting.

What happened:
Hello, @static_user.
Expected:
Hello, @static_user.

Fixed by replacing '@' for '@'

Instagram Updated Front-End

Emoji button added to the same form as the comment box and post button.
Fix check message actually sent

Handle popup

Patched: When going to Instagram's home page a popup doesn't appear to some users.

Patched send messages and scroll

Patched sending messages - Does_mention inside a statement not being executed because of no limit
Patched scrolling because javascript wasn't loading all html to find the element which was returning NULL

Quick fix in weight's default value

Weight's default value from None to 90 because was raising error if not "Save Only" and no weight was specified

Solved patch by executing JavaScript to scroll down

Added support for chars outside BMP, patched scroll and configs shortcuts

ChromeDriver doesn't support chars non-BMP so I had to execute it in the
browser directly in javascript.
Scroll would redirect to a user profile if their username was too big.
Some configs would do unnecessary work so it is patched now.

Patched language decimal separator

For example in english followers would be 1,570. In portuguese it would be 1.570

Added intervals, cookies, default language, executable location

Added triangular random intervals defined by user
Save and use accounts' cookie to auto-login and prevent Instagram from
finding suspicious activity
Added Default Language's Option
Added Executable Location's Option

Patch searching connections

While searching for connections (followers/followings) if someone had a long username it would click on it because Google Chrome's clicks at the center of an element.
