Replace web cdn references to maven coordinates

[nagavijays]

In Vorto repository, webpages uses direct cdn references, instead replace it with maven coordinates to bundled it together.
For e.g in server\repo-ui\index.html

<link href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.2.0/css/font-awesome.css" rel="stylesheet" type="text/css" />

can be replaced with

<script type="text/javascript" src="webjars/font-awesome/4.2.0/css/font-awesome.min.css"></script>

by adding respective maven coordinates in pom.xml

<dependency>
    <groupId>org.webjars</groupId>
    <artifactId>font-awesome</artifactId>
    <version>4.2.0</version>
</dependency>
