Create a crash reporter

[tylerjwatson]

There is a need for TSAPI to inform us of a crash report. The crash report will be in JSON format and submitted to a TShock endpoint for the purposes of finding server-breaking exploits before they have a chance to ruin the multiplayer experience for everybody. The mechanism is opt-out, but enabled by default, and will generate a 'crash dump' and save it to a subfolder of terraria called crashes.

Optionally, the crash reporter will include a memory dump of the calling process to help us find bugs in TShock.

Structure

The following information is due to be collected in this first pass:

[ ] OS Information (Type, bit-depth, platform, version)
[ ] Hardware information (Memory capacity, CPU count)
[ ] Software information (TSAPI Heapsize (?), Exception Information, stack info)
[ ] Heap information (core dump)
[ ] Metrics (Number of players, capacity, plugins loaded & versions, mostly TBD)
[ ] Auxiliiary Information (ServerLog.txt, as well as others)

Method

1. On exception, a system profile is generated
2. Optionally, a memory dump is created
3. The payload is zipped, and stored inside crashes as crash_{datetime}.zip
4. JSON payload is submitted to webservice
5. Crash dump is submitted to webservice
