😤 Match paths of existing website

[ezwelty]

The following path changes are proposed for backwards compatibility with the existing website (and all the links in the wild to said website):

• /about/project -> /about
• /about/press -> /press
• /about/share -> /sharing
• /about/data -> /data + /datasets (combines both pages) Deprecated alternate paths /maps and /inventories are ignored.
• /about/dataset/:id -> /imports/:id
• /entry/:id -> /locations/:id
• /entry/new -> /locations/new
• /entry/edit -> /locations/edit
• /account -> /users/edit
• /login -> /users/sign_in
• /signup -> /users/sign_up
• /password -> /users/password
• /password/reset -> /users/password/new
• /password/set -> /users/password/edit (API update required)
• /confirmation/new -> /users/confirmation/new
• /confirmation -> /users/confirmation (API update required)
• /review/:id/edit -> /reviews/:id/edit
