v0.0.4

Bump version and update .gitignore

v0.0.3: Require appsignal gem before requiring appsignal/elasticsearch

Since the appsignal-elasticsearch gem uses the same Appsignal namespace
as the appsignal gem, we need to require 'appsignal' before requiring
any of the appsignal-elasticsearch files. If we don't do this, then apps
using this gem will have trouble finding namespaced classes/modules such
as Appsignal::Config.
