Fix bug in ntfs parser (Velocidex#643)

Incorporates Velocidex/go-ntfs#29

Update version for release. (Velocidex#610)

Launcher dedups parameters now. (Velocidex#562)

Cleans up the VQLRequest a bit by removing redundant parameters.

Implemented a client KillKillKill message. (Velocidex#517)

This causes clients to be hard killed and refreshed. It will remove
the ring buffer to ensure the client is reachable again.

Also added extra safety to ensure the client executor loop is always
active. If any part of the loop exits - due to bug or exception, the
client will immediately suicide. The service control manager should
restart the client and bring it back to an operational state.

HTML report generator may produce arbitrary html. (Velocidex#489)

Since reports are stand alone files we can allow artifacts to produce
arbitrary html. This allows JS and CSS to be created by the artifacts
themselves.

Made some downloads optional to speed up sync. (Velocidex#425)

Add logging for access to the /public/ directory. (Velocidex#400)

Prepare for 0.4.3 release. (Velocidex#368)

Up version 0.4.2 for release. (Velocidex#313)

Added a bash shell artifact to support linux. (Velocidex#292)
