In order to make the license that applies to each file as clear as possible, and to be consistent with elasticsearch, we are adding Apache 2.0 license headers to the top of each file.
Existence of this header is enforced by eslint and tslint and missing headers were automatically added in the last commit by running:
```
node scripts/eslint --fix && node scripts/tslint --fix
```
* [typescript] add typescript support for the server and browser
* [ts-jest] upgrade to latest version
* [jest] support test.tsx files
* [jest/ts] modify `ts-jest.tsConfigFile` config based on filePath
* [types] use correct major version of minimatch types
* [jest] add ts support to x-pack jest config
* [ts/projects] fix tsconfig.json not found error message
* [optimizer/ts] use lowercase jsx option
* [tsconfig] remove ui/* alias
* [plguin-helpers] remove mention of `buildSourcePatterns`
* [plugin-helpers] expect typescript to be a devDep
* [dev/build] place transpile tasks next to each other
* [ts/x-pack] add common and server directories to ts project
* [dev/ts/project] use a limited set of globs to find tsconfig files
* [eslint] unify resolver configs
Our eslint resolver settings currently rely on the fact that we define
our resolver with a string globally, and an object in the overrides.
This causes the override value to completely override/replace the global
setting, which is desired, but when the global setting is converted to
an object they are merged, causing both resolvers to run.
This is a problem because some dependencies in the UI side of things
will resolve with the node resolver, but will resolve incorrectly
because they are intended to use some webpack specific override.
While trying to add TypeScript I needed to pass argument to the node
resolver which uncovered this issue. The change here moves us away from
using the node resolver directly and instead uses the kibana resolver
with `forceNode: true` set when linting server code and `forceNode:
false` when resolving imports that will be handled by webpack.
* [import-resolver] use object spread operator
* [uiExports] migrate uiApp "uses" to explicit imports in apps
* [uiApp] update tests for getModules() method
* [optimize/uiExports] improve naming and comments
* [uiExports] sort imports so they load in the same order as before
* [testHarness] load hacks when testing in the browser
* [x-pack/uiExports] use new uiExports modules
* [testHarness] describe why we import uiExports/hacks
* [optimize] remove needless [].concat()
* [optimize/createUiExportsModule] string.includes > string.indexOf
* [uiExports/createUiExportsModule] remove needless capture of module exports
