[core] restructure to allow PIP packaging

OK - so I have to admit I *hate* the fact that PIP seems to require a
subdirectory named like the library.

But since the PIP package is something really nifty to have (thanks to
@tony again!!!), I updated the codebase to hopefully conform with what
PIP expects. Testruns so far look promising...

+"""Displays the price of a cryptocurrency.
+
+Requires the following python packages:
+    * requests
+
+Parameters:
+    * getcrypto.interval: Interval in seconds for updating the price, default is 120, less than that will probably get your IP banned.
+    * getcrypto.getbtc: 0 for not getting price of BTC, 1 for getting it (default).
+    * getcrypto.geteth: 0 for not getting price of ETH, 1 for getting it (default).
+    * getcrypto.getltc: 0 for not getting price of LTC, 1 for getting it (default).
+    * getcrypto.getcur: Set the currency to display the price in, usd is the default.
