adding ability for users to choose display their chosen license on the public page

for OpenSourceFieldlinguistics/FieldDB#1047 and fixes OpenSourceFieldlinguistics/FieldDB#207 now that the public urls are ready we can make sure that the user's corpora have terms of use so that they conform to EMELD best practices.
Adding more links
putting in a quote from EMELD about why we have terms of use on corpora
added EMELD why license info
put in tabs for the terms of use and the why of terms of use
more details on why have terms of use
TODO add parameterization to use different lexicon servers
moving search.js into the libs, and out of the angular website so it doesnt get lost in a website refactor
for OpenSourceFieldlinguistics/FieldDB#1042 temporarily put searchdev online so we can hit it client side until the utf8 workaround is gone
for OpenSourceFieldlinguistics/FieldDB#1054 added anonymous team documents to dbs that were missing them with anonymous gravatars, this makes the gravatars more unique by using the pouchname.
if the public user cant see the data, we are not indexing it until the OpenSourceFieldlinguistics/FieldDB#1042 utf8 workaround is gone. this means we have to handle errors in the search widget
