Merge branch 'master' of https://github.com/singularity-viewer/SingularityViewer.git
Limit sMaxPipelinedRequests changes to once per 40ms, plus code clean up.

Mostly renaming stuff and moving static variables to class AIPerSerive.
Preparation for AIPerService::checkBandwidthUsage.

Don't pass arguments to wantsMoreHTTPRequestsFor, but use globals in
llmessage: AIPerService::sHTTPThrottleBandwidth125 and
AIPerService::sNoHTTPBandwidthThrottling instead.

This is needed later on.
Moved a part of AIPerService::wantsMoreHTTPRequestsFor to a new function.

The new function is AIPerService::checkBandwidthUsage.
No functional changes were made.
Add HTTP bandwidth throttling for every other responder.

Most notably getMesh (the only one possibly using any significant
bandwidth), but in general every type of requests that just have to
happen anyway and in the order they are requested: they are just passed
to the curl thread, but now the curl thread will queue them and hold
back if the (general) service they use is loaded too heavily.
Made compiler detection more reliable and cleanup clang warnings
fix a buggy
Fix initialization list order (compiler warnings)
Fix issue a different way and supress new gcc 4.8 warning
Sanitize cmake, cleanup develop.py
Merge remote-tracking branch 'LiruFox/master'
Minor improvemnt of coding style.
AIPerService improvements.

* Removed the 'RequestQueue' from other PerServiceRequestQueue occurances
  in the code.
* Made wantsMoreHTTPRequestsFor and checkBandwidthUsage threadsafe (by
  grouping the static variables of AIPerService into thread ThreadSafe
  groups.
WIP: Added AIPerService::Approvement
WIP: comment out llasserts.

This way my master isn't totally broken, at least ;).
