If a block like this is passed in as the "Input":

```
1
2
3
```

what slack actually is doing is this:

\n
1\n
2\n
3\n

since there is a newline character directly after and before the respective start and end.
This can be "fixed" by not including the newline when you type it:

```1
2
3```

but that doesn't look as clean. It would be simple to strip out a start and end character if they are '\n', but would it be too confusing?

When trying to use a new language, it's hard to guess what Sphere Engine is looking for in a string.

Add a way to specify a simple string like python, and have the bot return possible matches.

Ideally, it could do this as part of the normal code submit. If only one option came back, it would use that one, but if multiple did, then it would error and show the possible language options.

This issue was originally discovered 2017-10-23, but apparently never logged on Github.

If this is passed to compilebot:

@compilebot python

while True:
  pass

compilebot will correctly return:

@Rycieos: There was an error processing your code:
Time limit exceeded

But, if this is passed:

@compilebot python

while True:
  print("test")

compilebot will never appear to return anything.

What actually happens is that the text the bot is trying to send to Slack (when the compile times out) is too long and the connection breaks. Slack's docs (https://api.slack.com/methods/chat.postMessage) suggest that "a single message should be no larger than 4,000 bytes".

An easy fix would be to truncate the message after a certain number of characters. Slack's 4,000 byte limit claims to be for the text field, so chopping anything larger than 4,000 bytes to 3,950 or so and adding a "message was truncated" message is probably the best solution.
