Favicon location

Favicon location

This PR is used to change favicon to point to /favicon.ico url.

This is supposed to be the default location for geOrchestra's favicon.

Resolving :

• All applications should use the global favicon georchestra#4087

Altering default behavior.

In order to change default location, we can implement it with a custom script, modyfing /favicon.ico infollowing html files to the new location using a tool like sed.

Files to change :

# /usr/local/tomcat

./webapps/mapstore/api.html
./webapps/mapstore/embeddedTemplate.html
