Compress images using xz instead of gzip (#1018)

Browse Source 
The xz compression allows higher compression rates and higher speeds,
a quick measurement lead to this numbers:
gzip --best: compression 131.11s, decompression 9.797s (299M)
xz -3 (single thread): compression 95.13s, decompression 14.902s (228M)
xz -3 (multi thread): compression 12.146s, decompression 14.902s (228M)
