Fixed updateInstances() when there are none (should also update).
Created a tools module under a "tools" Maven profile, moved the other three modules to a separate profile that is active by default.
Added log4j.properties.
Added first tool, HttpResourceMonitor. Sends an HTTP request over and over and logs changes in responses.

Usage:

HttpResourceMonitor [host [resource]]

where
* host is HTTP host (default: "localhost")
* resource is path to resource on the host (default: "/")

Added two health checks:
(1) verifies that JCR Resource Resolver Factory and JCR Installer components are active
(2) verifies that the above components have correct search path configurations
Added HealthCheckMonitor which tries to run health checks until they all succeed. Minion now announces self only after all health checks pass.
Added health check verifying that all bundles are active.
Assume config not null in SearchPathTest instead of if-check.
Added scripts for configuring minion instances via cURL (for help run with --help):
- setup-minion-repo.sh: prepares Minion repository by creating the necessary directories and uploading bundles to install
- setup-minion-configs.sh: configures Minion instances' JCR Installer and JCR Resource Resolver Factory components
Added o.a.s.junit.healthcheck bundle
Scripts can now be executed from other directories.
