Update vendor github.com/boltdb/bolt to take care of the issue #1354.

* Use local folder for xgo

* Always do crosscompile and testing to fail early

* Added mips* values for boltdb

In order to get master building again I have applied these 2 additional
files to boltdb. This should get dropped when
https://github.com/boltdb/bolt/issues/656 gets solved.

* Dropped unused codekit config

* Integrated dynamic and static bindata for public

* Ignore public bindata

* Add a general generate make task

* Integrated flexible public assets into web command

* Updated vendoring, added all missiong govendor deps

* Made the linter happy with the bindata and dynamic code

* Moved public bindata definition to modules directory

* Ignoring the new bindata path now

* Updated to the new public modules import path

* Updated public bindata command and drop the new prefix
