added pom

[bogdad]

thanks!
used you teamcity rest client to solve task at hand, it was very heplful

added pom xml, so one could reference your work without building it using jitpack.io
like this:

maven:

<repositories>
        <repository>
            <id>jitpack.io</id>
            <url>https://jitpack.io</url>
        </repository>
</repositories>
<dependency>
        <groupId>com.github.paksv</groupId>
        <artifactId>teamcity-rest-api-client-java</artifactId>
        <version>master-SNAPSHOT</version>
</dependency>

sbt:

resolvers += "jitpack" at "https://jitpack.io"

libraryDependencies += "com.github.paksv" % "teamcity-rest-api-client-java" % "master-SNAPSHOT"

i didnot delete the lib folder, to make the pull request as light as possible
