RFR: Javadoc search broken after output files organization for modules

[Bhavesh Patel]

Hi,
     This is the fix for javadoc search that was broken after the output 
files organization for modules. As a part of the fix, search.js is 
updated to accommodate these changes.The URLs will be calculated 
correctly if --no-module-directories command-line option is used. I have 
tested the output for module and non-module directory structure. In 
terms of tests, we do not have much of automated testing in this area so 
only checking the variable that is set for the directory mode and the 
actual script changes are being checked. I have also tested the offline 
bundles and it works fine with the change.
