fixed EXT-5429 IM chat history of active tab in IM container is not updated when IM container is unminimized

--HG--
branch : product-engine

- Deleted unnecessary parameters (UIButtonImageTopPadding, UIButtonImageBottomPadding) from settings.xml and their usage in LLTabContainer

- Deleted triggers (LLIMFloaterContainer::processProperties and LLIMFloaterContainer::changed) due to LLIMFloaterContainer no more Observer

- Renamed class LLParticularGroupMgrObserver to LLParticularGroupObserver as the last one's name is more self explanatory

branch : product-engine

Fixed critical bug EXT - 4906 (Viewer crashes after group message was sent if close IM chat from message sender previously)

--HG--
branch : product-engine

add floater flashing, fix group icon sizes, fix click,some code cleanup, ect.
also I remove mIconCtrlWidth/Height since its kinda useless - mIconCtrlPad do the same thing...
IconSize will be btn_height-2*mIconCtrlPad - simple and good enough.

Sadly, we don't seem to have a commit hook for that.

Conflicts resolved by prospero:

C    scripts/farm_distribute

C    scripts/automated_build_scripts/build-linux.sh : resolved by
                     prospero, mostly kept the merge-right version in
                     the conflict, but there was one block of repeated
                     code from earlier that I removed.

C    scripts/automated_build_scripts/build-mac.sh : kept merge-right

C    indra/llcommon/llversionserver.h : svn revert

C    indra/newsim/llsimparcel.h : kept *both*... working had "setArea",
                    merge-right had exportStream and importStream

C    indra/newsim/llsimparcel.cpp : see llsimparcel.h

C    indra/newsim/lltask.h : working had LLTask derived also from
                   LLScriptResourceConsumer, merge-right had LLTask
                   dervied also from LLAgentPosition.  To resolve
                   conflict, derive from both.

C    indra/newsim/lllslmanager.h : kept merge-right (had an added comment)

C    indra/llmessage/llhttpnode.h : kept working (added the definition
                   of method LLHTTPNode::extendedResult)

C    indra/lscript/lscript_execute_mono/llscriptexecutemono.cpp
C    indra/lscript/lscript_execute_mono/llscriptexecutemono.h
                  : These two were resolved by si, in consultation with daveh


I also had to add the following stubs to
indra/newsim/tests/llgodkickutils_test.cpp in order to get it to
compile:

  // LLScriptResourceConsumer interface methods in LLTask
  LLScriptResource::LLScriptResource() { }
  LLScriptResourcePool::LLScriptResourcePool() { }
  LLScriptResourcePool LLScriptResourcePool::null;

  LLScriptResourceConsumer::LLScriptResourceConsumer() { }
  LLScriptResourcePool& LLScriptResourceConsumer::getScriptResourcePool() { return LLScriptResourcePool::null; }
  const LLScriptResourcePool& LLScriptResourceConsumer::getScriptResourcePool() const { return LLScriptResourcePool::null; }
  bool LLScriptResourceConsumer::switchScriptResourcePools(LLScriptResourcePool& new_pool) { return false; }
  bool LLScriptResourceConsumer::canUseScriptResourcePool(const LLScriptResourcePool& resource_pool) { return false; }
  bool LLScriptResourceConsumer::isInPool(const LLScriptResourcePool& resource_pool) { return false; }
  void LLScriptResourceConsumer::setScriptResourcePool(LLScriptResourcePool& pool) { }

  S32 LLTask::getUsedPublicURLs() const { return 0; }
  void LLTask::setScriptResourcePool(LLScriptResourcePool& pool) { }
