Add @return type and @param values in the comment docblocks

@aditya_anurag, I saw your patch and noticed some points to improve.

- Docblocks need a blank line between the first line such as * Implements hook_install_tasks() and the rest.
- Docblocks also need a blank line between @param group and @return.
- The descriptions for @param and @return are not inconsistent in the code. If you want to improve the docblock, Isn't it better to add descriptions to all of new @param and @return?
- @internal may not be necessary.

Please try seeing the documentation standard again.

Added patch for this issue. Also fixed some coding standard issues.

Thanks for the contribution!

This also appears to do some trailing whitespace fixing, which I guess is fine since we don't have (that I'm aware of) other patches working on this same code. Usually, we like to isolate whitespace fixes to their own issues because they break other patches.

One small bit of review:

This looks like an unintentional addition?

Hi dsnopek,

So I would just need to remove the unintentional addition correct? or is there anything more that needs to be changed?
