Unnecessary dependencies in the site example

[abelsromero]

While playing with the examples (btw, really cool one), I spotted the following dependencies which I think are not required when using maven-fluido-skin

asciidoctor-maven-demo/pom.xml

Lines 228 to 238 in de9491c

	<dependency>
	<groupId>lt.velykis.maven.skins</groupId>
	<artifactId>reflow-velocity-tools</artifactId>
	<version>1.1.1</version>
	</dependency>
	<!-- Reflow skin requires Velocity >= 1.7 -->
	<dependency>
	<groupId>org.apache.velocity</groupId>
	<artifactId>velocity</artifactId>
	<version>1.7</version>
	</dependency>

.

Also, there's a 1.7 version availble.
