0.0.2 HotFix PluginManager

PluginManager had some issues with not deleting the temps, copying the
module to it's needed place, and essentially working as
expected...should be fixed now! :-)
0.0.3 PluginManager Updated

- Admin modules are now using the filename's 'ModuleName.admin.php' to
denote they are admin modules. This usage is similar to the old
"Admin_ModuleName" class structure.
- PluginManager now activates
plugin correctly if __activate() exists and returns true, or if
__activate() doesn't exist at all.
- Multiple plugins can be installed
via the same upload. This is important for admin modules to be installed
with frontend bretheren.
- A new phpDoc comment has been added for
Plugin Headers: 'Relation'. This optional comment should be set to
either 'parent' or 'child'. Child meaning that it's pid (parent_id) is
set to whatever plugin has the same package BUT has a pid of 0 (Absolute
parent).
