Add sk89q-mvn2 repostory definition in pom.xml

[pragmatic]

Hi,

I tried to do a clean install of CHPex with a fresh install of the JDK and Maven, and I got the error:

[ERROR] Failed to execute goal on project CHPex: Could not resolve dependencies for project com.brothercraft:CHPex:jar:1.1.1: Failed to collect dependencies at com.sk89q:commandhelper:jar:3.3.2-SNAPSHOT: Failed to read artifact descriptor for com.sk89q:commandhelper:jar:3.3.2-SNAPSHOT: Could not transfer artifact com.sk89q:commandhelper:pom:3.3.2-SNAPSHOT from/to pex-repo (https://pex-repo.aoeu.xyz/): sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target -> [Help 1]

To get it to work, I manually added the below definition, taken from your CHBarAPI repository:

    <repository>
        <id>sk89q-mvn2</id>
        <url>http://mvn2.sk89q.com/repo</url>
    </repository>

I also initially got an error with the pex-repo, I had to change the URL to non-https, i.e. http://pex-repo.aoeu.xyz/

Please update your pom.xml to be newbie-friendly, and maybe consider offering a release download for those averse to compiling extensions.

Thanks!

I don't have a development setup right now, so it will be a while before I will get to this. I would like to fix it, though! If you submit a pull request or ask one of the Command Helper developers to do so, I'll gladly merge it.
