prestation list dedicated filter implemented.
Add save function to prestation list controller.
Working editable list but too heavy to display for thousands of lines
results. (>30s)
ui.bootstrap 0.11.0 tests in comment. 

Noticed navigation problem: i.e. systematically redirected to CONSTAT 
creation while navigating IMMEUBLE links to other resources. Seems
unrelated to date management but appears with ui.bootstrap 0.11.0 not
0.10.0.
Revert from ui.bootstrap 0.11.0 tests.
Language.
Pagination first draft.
