fixes to deploy
cleaned up pathway mouseover content
include sampledata/images in statics search path in local dev envs
removed local http get in can_access_image

It's fine to have the client request the image unconditionally, at least for
now. Eventually the dataset loader should check image availability at load time
and set a column in the db.
reimplement can_access_image using FileSystemFinder
added sorafenib kinomescan image to sampledata
added do_pathway.py to deploy script
improved db detail page header content

include entity name, type and id. implemented using a sub-template.
change date format and add user info to deploy log
network images
Merge remote branch 'origin/dev' into dave-sean-dev
