Enhancements for the jsdoc files published on the web

[AdrianVasiliu]

Future improvements over those introduced in https://github.com/ibm-js/jsdoc-amddcl/pull/38 may include (as already reported):

• Skiping the deepest level of {projectname} for the *.html files - additional level which is not present for the generated index.html files.
• Removing the duplication of *.js.html files (decor's ones duplicated in delite's doc etc.).
• Support for {version} also in the paths config param, just as it is already supported for packagePathFormat (e.g. https://github.com/ibm-js/jsdoc-amddcl/commit/f479384a8cd4fe5b8679153fdd1416ee74e0ac8f#diff-35b4a816e0441e6a375cd925af50752cR89), to avoid the need of manual updates of paths of each Gruntfile.js at each release of a new version.
• Automatic conversion of relative links in README.md (itself converted into jsdoc's index.html) such as "./LICENSE" into absolute links to the corresponding github files.

The issues are mentioned/discussed more in detail in the comments of https://github.com/asudoh/jsdoc-amddcl/commit/7a620847a762cb4ef236541d0f17730f49322d58 .
