Change file structures so that the interior modpol folder IS the portable modpol.

Added documentation of how to pre-define the modpath and the storage file.

+When calling modpol.lua from another file, one may wish to use 
+different functions than those included by default. 
+
+So far, 2 definitions need to be made BEFORE calling modpol.lua, the rest can be overwritten
+after calling modpol.lua .
+
+setup:
+----------------
+Define the global modpol table:
+modpol = {}
+
+the following 2 items *may* be defined, if they are not, then defaults will be used:
+========================
+--------------------
+modpol.get_script_dir()
+--------------------
+type: function
+
+defaults to: a function that can only work in linux
+
+usage: must return the file path of the modpol directory. If modpol is in a
+larger directory, such as a mod filesystem, make sure that the path returned is the "base" 
+modpol folder, i.e. the folder with all the original modpol files.
+========================
+--------------------
+modpol.storage_file_path
+--------------------
+type: string
+
+defaults to: topdir .. "/storage/storage-local.lua", 
+where topdir is the directory defined by modpol.storage_file_path 
+
+usage: if you wish to use another method of storage than that provided by default, 
+then you can save a filepath to the storage script here.
