* Fixing the enable_gem.py and disable_gem.py commands
The project path wasn't taking into account when querying for gems,
templates and restricted directories registered with the project
Fixing the cmake.py add_gem_dependency and remove_gem_dependency methods
to properly detect a gem within a `set(ENABLED_GEM ...)` cmake variable
Also updated the add_gem_dependency to add the gem right before the end
marker of ')'
Updated the remove_gem_dependency to remove each instance of a gem with
a content that is in between in the `set(ENABLED_GEM ...)` cmake
variable
* Correct Typo in manifest.get_registered doc string
