Pastebin Error

[Foorack]

The error occurs here. https://github.com/r-clancy/PlugMan/blob/master/src/main/java/com/rylinaux/plugman/util/PluginUtil.java#L260

The plugin tries to throw the aliases variable to a List<String> while it apparently is a List<Integer>. The code should properly check the variable is a List and that each sub-variable is actually a string.

I can prepare a fix for this in a few days.
