Update Teca profile (shorturls/symlink update)

Commit ["Symlinks!"](https://github.com/alfateam123/Teca/commit/7eba8b6c42956598e13733c1cb28f8f5d4de49bd) in alfateam123/Teca introduces the shorturl extension,
Teca profile was not functional on sites generated with said option turned on.
A [later
commit](https://github.com/alfateam123/Teca/commit/d368a3d1664db2f2bae2bba21b242e5471297e76) lets Dumper
know if an user turned the option on and, in case, what is the url used for short urls/symlinks.
