* Adds Error Handler
Adds a /world/Error proc to handle runtime errors. This proc replaces
the normal runtime logging behavior, providing the following
improvements:
- Adds timestamps to runtimes
- Pads or omits certain lines
- Continues logging runtimes after the 99th (with less info, as provided
by BYOND)
- Adds ckey and accurate xyz to usr info
- Continues including usr info after 19th runtime
- Silences spammy runtimes (by default, a runtime that occurs 10 times
in 10 minutes gets ignored for the next 10 minutes)
* Adds runtime viewer
Also fixes a minor mistake in the error handler
* Sanitizes HTML in Error Viewer
Also removes the stray return from the end of the error handler
* Prettifies Error Viewer
Now uses browser datum and some extra bits of formatting, inspired by
the changes made by @PJB3005
* Error Handling Improvements
- Skipped error counts now show up in the error viewer
- Proper runtimes caught by a process are now sent to the main error
handler
- The error handler and viewer can now handle a provided src, such as
one from a processing runtime
- Moved some info generation into helper procs
