XML corrections

French corrections
Correct Aleric's mistype of tool_tip
Add support for uploading .anim files.

Mostly works, but
indra/newview/skins/default/xui/en-us/floater_animation_anim_preview.xml
needs work (the 'Name:' should be at the top, not the bottom).

Also, it asks if you want to upload this as temporary. It shouldn't do
that.
Pass LLControlGroup* to AICurlInterface::startCurlThread instead of each Debug Setting separately.
Moved connect limits per service to AIPerServiceRequestQueue.

Added AIPerServiceRequestQueue::mConcurrectConnections and
AIPerServiceRequestQueue::mMaxPipelinedRequests.
Renamed AIPerServiceRequestQueue[Ptr] to AIPerService[Ptr]

This because AIPerService now contains a lot more than just the request
queue.
update and fix all spanish translations files
add new all spanish translations files
Add CURRECY_TEXT definition and handling for internationalization
Derived classes may access this.
Little fix in some spanish translations
Finally allow a very small communicate window to be saved and restored properly at the size the user set it.
Merge branch 'master' of github.com:singularity-viewer/SingularityViewer

Conflicts:
	indra/newview/hippogridmanager.cpp
	indra/newview/hippogridmanager.h
Make sure we only do a show in inventory if a sinle item is given. Enything else makes no sense or bombs
Merge remote-tracking branch 'aleric/master'
Less overshoot in HTTP bandwidth graph for higher values.
Add debug function 'is_single_threaded'

Usage:

AIThreadID foo(AIThreadID::none);

...

  llassert(is_single_threaded(foo));
...
  llassert(is_single_threaded(foo));
...
etc

The first call to is_single_threaded(foo) remembers the thread,
and after that it is enforced that any call from anywhere that uses foo
is done by the same thread.

If AIThreadID::none is omitted then the thread is enforced to the thread
that creates the AIThreadID.
Compile fix.

Move the destructor (and copy constructor while I was at it) to the .cpp
file in order to avoid instantiating the destructor of
boost::intrusive_ptr<ThreadSafeBufferedCurlEasyRequest> from a header,
which would require the class ThreadSafeBufferedCurlEasyRequest
to be defined in that header, which is unnecessary. In other words,
this avoid the need to include "aicurl.h" in headers using
AIPerService[Ptr].

Also fixed indentation of a comment.
Stats floater fix up.

Add '(UDP)' after Objects, to show that this is UDP bandwidth.
Do not add the received HTTP texture bytes to gTextureList.sTextureBits,
making it (and the 'UDP Textures' graph) indeed pure UDP.
Don't call LLInventoryModelBackgroundFetch::backgroundFetchCB unnecessarily

Remove LLInventoryModelBackgroundFetch::backgroundFetchCB from
gIdleCallbacks when we don't need it anymore.
Add throttling to HTTP inventory (bulk) fetching.

Call AIPerService::wantsMoreHTTPRequestsFor in
LLInventoryModelBackgroundFetch::bulkFetch to determine if curl is ready
for the next batch or not, instead of using inaccurate heuristic code
that is just guessing a bit.
