NIHVIVO-1954: Done some markup refactoring changing ID's into classes.

Also,  in some cases I wasn't able to change id selectors because these are used temporarily due to the custom jsp tags (<v:input>) 
for editing forms which require an id and do not allow a class. This will be 
removed once we refactor the editing forms to Freemarker
