Regard less of true story of Moraya Gosavi, that doesn't make anysense to say "Ganpati Bappa Moraya"...
Actually splitting the word Moraya as "Mhora ya" means "come ahead and bless us" make sense here.
Thus "Ganapati Bappa Moraya" means
"Lord Ganesha Bless us"
(Here Bappa is used for Lord...)

Yes, Ganapathi is another name of Lord Ganesha which means the Lord/Owner of all Shiva Gana (The army of Lord Shiva).
Bappa means Father/Lord and Morya refers to the greatest devotee of Lord Ganesha.
To understand the meaning completely, "Ganapathi Bappa Morya" alone is not sufficient.
The entire stanza "Ganapathi Bappa Morya, Purchya Varshi Laukar ya" is needed, which means "O Lord/Father Ganesha, come again next year fast".
