Title: Respect hidden file convention when loading arenas

[Apache Subversion](http://en.wikipedia.org/wiki/Apache_Subversion) is a revision control system.
Its normal operating procedure is to add a hidden .svn file to every folder to be versioned.

Before:
```
plugins/
CaptureThePoints.jar
CaptureThePoints/
Arenas/
```

After:
```
.svn/
plugins/
.svn/
CaptureThePoints.jar
CaptureThePoints/
.svn/
Arenas/
.svn/
```

The structure of the `.svn` folder is as follows:
```
.svn/
dir-prop-base
entries
prop-base/
props/
text-base/
tmp/
```

CaptureThePoints does not respect the linux/unix convention that all files that start with a `.` are hidden files.
Hidden files should not be accessed unless your application is looking for them specifically.

Without this patch, CaptureThePoints takes the files in `.svn` folders and attempts to make arenas from them.

This is a compatability patch. While Subversion is the example, there may be hidden files on other systems that CaptureThePoints should not be accessing.
