* fix CLI help text for unlocking

fix regression with docRoot / admin API
* docRoot/jspath passed to rpc/api ParseApis, which passes onto adminApi
* docRoot field for JS console in order to pass when RPC is (re)started
* improve flag desc for jspath

common/docserver: catch http errors from response

fix rpc/api tests

common/natspec: fix end to end test (skipped because takes 8s)
