Support half bathrooms and bedrooms when creating a listing

Closes #497

Summary of change

• Can now create a listing and submit a form with half bedrooms and bathrooms.
• Also added red asterisks to required fields.

Testing/Verification

When creating a listing:

• Text fields for bedrooms and bathrooms should support whole numbers and decimals ending in 0.5 (but no other decimals).
• Text field for maximum people should still only support whole numbers.
• Should see red asterisks next to required fields (please double check if the required fields are correct!)

Looks great! I think adding the red asterisks was a nice touch. A few tiny comments:

Yeah, great touch with this, I'll link #498 to it as well because I think this addresses the concerns I brought up with that issue!
