Update our realstate registration and search feature

1-) Create a separate entry for the For Rent "Alugar" on the form. so that we don't have to use the same field as property price. 2-) user experience enhancement: multiple photos upload. Create an option so that they Realtor can upload all the photos at the same time. 3-) Add a share facebook button on property listing details. 4-) investigate to see if the number of garagen spots "vagas" can be reduzed to one on the registration form. 5-) Add an Admin page so that I can manage username and password. (can be added after you login next to "Relatorios" and Sair) 6-) add the actual property details url id on the contact form of the property details pop up page. give me a competitive estimate to see if I can afford to make these updates. 7-) Add a log off session after 15 minutes of inactivity on the registration form. 8-) fix a small bug (update price drop down menu) price drop down bug fix.
