rewrote the initpkg mechanism and moved py lib implementation files to

_py/...  with py/__init__.py containing pointers into them

The new apipkg is only around 70 lines of code and allows
us to get rid of the infamous "py.__." by regular non-magical
"_py." imports. It is also available as a separately installable
package, see http://bitbucket.org/hpk42/apipkg

+submit failure or test session information to a pastebin service. 
+
+Usage
+----------
+
+**Creating a URL for each test failure**::
+
+    py.test --pastebin=failed 
+
+This will submit test run information to a remote Paste service and
+provide a URL for each failure.  You may select tests as usual or add
+for example ``-x`` if you only want to send one particular failure. 
+
+**Creating a URL for a whole test session log**::
+
+    py.test --pastebin=all 
+
+Currently only pasting to the http://paste.pocoo.org service is implemented.
