[Feat] Load Project without using Vuex replaceState

[zachzoup]

Is your feature request related to a problem? Please describe.

The projectActions.loadVueggProject action uses the Vuex replaceState function, which complicates implementing this project into an existing application using Vuex.

Describe the solution you'd like

Modify the projectMutations.updateProject method to allow updating more properties than just the title.

Describe alternatives you've considered

Could potentially create a new method, though renaming the existing updateProject method to updateProjectTitle might be a bit clearer.
