Short URL, permalink and SEO

[cgiovando]

Some features that would be nice to implement for sharability:

• URL shortener (a la osm.org/go/..)
• permalinks that work with filters, to make it easier for anyone to share specific data views
• nicer URLs with semantically structured parameters (e.g. http://osm-analytics.org/#/show/ecuador/buildings/recency instead of http://osm-analytics.org/#/show/polygon:lwmnM~zbKei%7D%40uslAo%60k%40syzBi%7Bd%40fcB%7CtG%7DqrAvbfAk%7BmAcu%60Ae~%40zifBkcb%40%60naBufgAryv%40%60rf%40vrvDctb%40tu_%40uwsAvd_B%7DeSn%60Vwsl%40jndByfs%40rmnC%7DwDnhwBx%7C%7DAjesEvtcLfpO%60%7DpLksyEduF%7DkLdpsAnyv%40nrXza%40%60dwA%7Bvs%40ey%5BidjA%60~d%40ad%60%40%7B%7DHia%60Ab~~Aa_q%40zoNyghA%7DgvAej%7C%40akfF_oe%40%7C%60Mom%7B%40gjvAu%7B~EiulA/buildings/recency)
