  FLUID-5010, FLUID-5012, FLUID-5013, FLUID-5014, FLUID-5017, FLUID-5018: Correction of numerous problems with IoCSS uncovered by early UIO refactoring work
  FLUID-5010: Fixed jira numbers.
  FLUID-5010: Updated jira numbers in the test file that demonstrates described issues.
  FLUID-5010: Replaced some manual fat panel options mapping with IoCSS. The remaining fat panel options mapping and UIO mapping will be replaced by IoCSS as well once the required features are implemented.
  FLUID-5014: Created test cases to produce the IoCSS issue with passing one source value to several targets.
  FLUID-5013: Fixed the wrong "distributeOptions" in the test case.
  FLUID-5012, FLUID-5013: Created unit tests to re-produce the issues described in FLUID-5012 & FLUID-5013.
FLUID-5010: Replaced more manual options mapping code with IoCSS. Ran into an issue with passing options assigned in preInit or finalInit and created FLUID-5025 for that. Hopefully after it's addressed, the remaining two other manual mappings can be replaced.
