* Determine MB project root directory relative to source directory of build scripts

* Support calling build-driver! as a -X fn, and support dirs outside of modules/drivers

* Support loading 3rd-party driver manifest files at (dev) launch

* Fix log4j not working on latest version of CIDER (unrelated)

* Fix dissoc

* project-root-directory is supposed to be a string

* wip for licenses

* Lots of changes

- bump clojure.data.xml to prevent illegal access
- had to change navigators because of this
- switch to full text of license
- algo is now:
  1. check for a license file in jar
  2. check for an override pointing to a license file locally in
     resources
  3. Check pom file for license information and just use that

can be invoked as:
```bash
% clj -X mb.licenses/process :classpath \"$(cd ../.. && lein classpath)\" :backfill "\"overrides.edn\"" :output-filename "\"backend-licenses.txt\""
License information written to  backend-licenses.txt
/Users/dan/.m2/repository/net/jcip/jcip-annotations/1.0/jcip-annotations-1.0.jar  : No license information found.
org.clojars.brenton:google-diff-match-patch  : No license information found.

% wc backend-licenses.txt

* xml/parse without the strings

* Add tests

* remove comment form

* namespace comments

* readme

* instructions to create backend license files

* Add version information to the build script

need to either yank it out of the separate project or just use it as a
local root. not sure which

todos: move to s3 once i get access and figure out the proper bucket
       copy to a place so it ends up in the jar
       generate frontend versions as well

* Build frontend and backend license files

put them in the jar at
META-INF/leiningen/metabase-core/metabase-core/license-frontend-third-party
META-INF/leiningen/metabase-core/metabase-core/license-backend-third-party

need to be named ^license.* for lein uberjar to pick them up

* Rename and reformat

* remove old stuff

* combine with a newline

* Tests ensure all jars have an identifiable license

* Extra information if backfill is malformed or missing

* correct name for apache2_0 backfill

* print out classpaths in CI

* print

* see whole classpath. it's empty on ee for some reason

* assert they are there

* Get deps before attempting classpath

for some reason the first one fails. but subsequent re-runs work.

* loop on deps until satisfied

* Include message if cannot satisfy

* include all drivers when getting deps

* rearrange ns docstring

* Hoist functions on pom inside of `with-open` on the input streams

* Update to inversion of pom parsing

* Move to nio from java.io

* Integrate driver JAR strip-and-compress logic into build-driver script

* Fix missing import

* Minor improvements

* Mega build script improvements 2

* Fix Circle

* Mega build script improvements

* Look for project.clj to determine root directory since we delete .git on CI for speed

* If .git folder is missing (i.e., in CI) fail gracefully

* Don't need to generate version file to run Cypress tests, right?

* Build uberjar step can cache version.properties
(so the Cypress test steps don't need to generate it again)

* Flush caches

* Update uberjar cache key
