ui tweaks in company list, search, sidemenu

in company list view:
—android-close icon replaced by cuter ios7-close-empty
—fixed the prompting placeholder text since search bar searches entire
company object properties, not just the name
— instead of displaying industry below name and room at side, shows
room below name and only star at side (industry would sometimes be cut
off on mobile)
sidemen:
— greyed out the survey option and disabled the link, since the survey
isn’t actually hooked up to anything
