* 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
* Added ExecuteWithLockErrorHandling() which returns an outcome with the actual error we get from python so that we can expose that to the UI.
* Added cmake pybind.
* Get gems now calling get_all_gems and alphabetically sorting the result.
* Added get enabled gems function which first gets the cmake enabled gems file path from the project path and then the list of gem names that are enabled.
* Some changes to the enable and disable gem functions.
* Add Add/RemoveProject to Python Bindings
* Support Project, Add, Remove, Copy, Delete
* Open parent directory when duplicating to discourage path in owning dir
* Remove extra connects for new projects button
* Center project image
