/chat route

• page is not responsive, seems to have a fixed width
• UI seems generally broken/buggy (pretty much nothing works? am I meant to be reviewing this route?)

/location route

• Sometimes, sending a message does not show the message to the recipient immediately (have to exit the message window and return to see it, or send back a message to the other user, and then the previously received messages show up)
• why does clicking on the chat icon next to the user in the "Friends" menu open up a group chat? Is there only one group chat shared between all your friends?
• There are no user names in the group chat, no way to know who is saying what
• layout / style of the chat window looks unpolished

All these location bugs have been fixed. The styling still could use some work, but we need this PR in for the added functionality ASAP.
