Closes #3549

Improves the search so you can filter on more things.

• You can now enter from:me to search for messages only created by the current user.
• has:star returns messages that are starred by the current user
• is:pinned or has:pin returns messages that are pinned in the current channel
• has:url or has:link returns messages that contain a link
• has:location or has:map returns messages that have a location attached
• before:dd/MM/YYYY, after:dd/MM/YYYY and on:dd/MM/YYYY return message that were created before, after or on the provided date respectively. You can also use dashes - or dots . instead of slashes.
• order:asc sorts messages by ascending timestamp. You can also use order:ascend or order:ascending
• order:desc sorts messages by ascending timestamp. You can also use order:descend or order:descending.

There is no indication in the UI that is this possible though.

I've also converted the coffeescript to js since I know you guys are doing this step by step.

@lucasvanhalst this is really cool! So with all of this we kind of need a cheatsheet quick help thing there in the search.

[sampaiodiego]

that is indeed really cool!

[lucasvanhalst]

Yeah something like this @geekgonecrazy

[geekgonecrazy]

@lucasvanhalst ah yes! Agreed, that looks nice

I'd like to see 2 things here:

1. add instructions, maybe here
2. highlight filters ins searchbox (like in slack)

Date-filter seems buggy:

I create two new seperate issues

[geekgonecrazy]

@alfredbez we'd welcome another PR to add that. 😄

It's true that the date filters don't won't properly. They did on my test environment of course.. God I hate time zones :D

To follow up, the dates still work but it's not in the American format. It is dayday/monthmonth/year, so for Feburary 11th, 2017 the search would be: on:11/02/2017.
