Usability improvements:

- Include bundle name in cache key
- Emit a few more messages at 'info'

Truncate Gradle args when constructing cache key (gradle#71)

Cache keys have a hard limit of 512 characters, so we need to ensure that we don't generate a key longer than this.

- Remove excess whitespace
- Truncate to 400 characters

Fixes gradle#70

v1.5.1

Include Gradle invocation arguments in cache keys (gradle#69)

This permits a new cache entry to be persisted when a subsequent Gradle invocation does more work that an earlier invocation.

Fixes gradle#68

Rename action from "Gradle Command" to "Gradle Build Action"
