Update for new builds site with beta builds
Add note about stb to 3rd party credits in LICENSE and docs
Update things to point to the new builds page available
Install UI.pdb to get better callstacks (zip distributes all pdbs)
Make installer add thumbnail & file ext registry entries by default

* This might be the wrong thing to do, I've changed my mind on this a dozen
  times. I think most people will want these, and I don't think it's a bad
  thing to include it as the default setting - people can still go to
  customise and unselect it. I thought most people would do custom and then
  opt-in since most will want it, but I suspect (from watching people run
  the installer) that most people hit typical, and so don't get these.
Pack-in d3dcompiler_47.dll with distribution. Refs #81
Convert capture timestamp to local time
Fix bug with pixel history not allocating enough pixel data store
Use the correct/matching row pitch value when reading from Map()
Correctly fetch coverage, primitive ID and frontface. Refs #81

* PSInput must be the first thing in the function signature to match the
  output of previous stage, but we snip out the above SV semantics and
  fetch them separately to get the right values and not hit any weird
  compiler errors.
Update snippet-adding code for multisampled types
Remove toolbar debug pixel button
Batch update for bits of documentation that were out of date
Reorganise 3rdparty, include breakpad with sln, drop mhook. Closes #84
Inline the couple of DIA interfaces used so USE_DIA isn't needed
Comment capture options, deprecate CacheStateObjects. Closes #61
Pass through chunk serialiser and log state to ResourceManager
Fix for crash if frame capture is queued & process fails to create
Display a tooltip over registers with their current value
Add selection of primitive to pixel debug from pixel history

* This means when multiple fragments are writing to a pixel you can choose
  precisely the one you want to debug, rather than the debugging always
  running the approximately last fragment to pass
