Allows Project::all() handle more than 100 projects
Update documentation
Added option to check ssl host
Corrected the url of the request for the create method
Altered the array filter on create method to allow indexes with false equivalent content

I was trying to create a private project, so I had to define the 'is_public' index as false in the params array, but the array_filter function was eliminating it so my projects were being created as public projects.
I added a callback function to the array_filter so that it only eliminates the null indexes of the params and not those that are equivalent to false.
