frontend: latest compiled css and js

Harden whitespace in log messages to show newlines, tabs, and spaces. Due to the additional and inconsistent height of log messages, the other columns are vertically aligned to the top rather than the middle.

Convert "message" searches to boolean "and" instead of "or" queries.

js tests: simplify js test html

changelog: add changelog stub

rule engine: add support for NOT rule

logging: fix logging for webhooks

validation: remove 0.4 report validators

forms: now that AE is open source this is not required

tasks: change sampling rates for something better suited for big amounts of data
