Trailscraper

_skipped because of release-problems_

Fixed

* Fixed various special cases in mapping CloudTrail to IAM Actions:
* API Gateway
* App Stream 2
* DynamoDB Streams
* Lex
* Mechanical Turk
* S3
* STS
* Tagging

Fixed

* Ignore record files that can't be read (e.g. not valid GZIP) in Python 2.7 (was only working in Python 3.* before)
* Fixed permissions generated for services that include the API version date (e.g. Lambda, CloudFront) (20)

Added

* Support for CloudTrail `lookup_events` API that allows users to generate a policy without downloading logs from an S3 bucket.
Note that this API only returns _["create, modify, and delete API calls"](https://docs.aws.amazon.com/awscloudtrail/latest/userguide/view-cloudtrail-events-supported-services.html)_
* `trailscraper download` now supports `--from` and `--to` flags to specify the timeframe that should be downloaded. Accepts precise (e.g. "2017-10-12") and relative (e.g. "-2days") arguments.
* `trailscraper generate-policy` now supports `--from` and `--to` to filter events to consider for the generated policy. Accepts precise (e.g. "2017-10-12") and relative (e.g. "-2days") arguments.

* Performance optimizations: `generate-policy` only reads logfiles for the timeframe requested

* Added `--version` command line argument

Changed

* Set more flexible dependencies

Removed

* Removed `--past-days` parameter in `trailscraper download`. Was replaced by `--from` and `--to` (see above)

Fixed

* Ignore record files that can't be read (e.g. not valid GZIP)

Added

* Support for Python >= 2.7

Changed

* Do not download CloudTrail Logs from S3 if they already exist in the target folder (9)
* Removed dependency on fork of the awacs-library to simplify installation and development

Fixed

* Bug that led to policy-statements with the same set of actions not being combined properly in some cases (7)

Added

* Basic filtering for role-arns when generating policy (3)
