Refactored/fixed bugs for Trajectory Controller #new
Begin setup of displaying prior trajectory stops. 
- Also, fix cookie bug and '@p.i' bug
add some testing with the long form linking
add functional trajectory form - still some potential bugs, espeically if none of Village, Site or Alt Village are entered. Validation are needed, though there was some problem with the each do loop in the trajectory view when they were attempted
Set up basic trajectory-chain styling and fix IdpTrajectory#prior_trajectories method
- Also refactor minor code and css stuff
add sprucing and style changes for trajectory form
fix little bug
fix export bug in gsi and idpt
remove gold_standard_identity/search_form fields that are now recorded in long form entries
Add callback to ensure all saved trajectories and gold_identities don't store blank strings for attribute values
