Fix: Set ph_office as default map and add map download

- Changed default map from gm_construct to ph_office in start.sh
- Added ph_office to mapcycle.txt as first map
- Added download_prophunt_maps function to install.sh to automatically
  download and extract the ph_office map (Workshop ID: 188818807)
- Maps are extracted using gmad_linux for immediate use
