Fix float point overflow when doing pass up

The old way of rounding floor(x/((float)sizeof(int)))*sizeof(int)) will
cause overflow when x is greater than 203672784. For example, if x is
203672792, the above expression will give 203672800. When this bigger
value is minus by parent_sent_pos, negative value can be generated
which is later assigned to an unsigned integer. This will cause the
whole learning fail. This patch fixes the above expression and a
potential network problem.

Merge pull request #349 from hal3/master

initial version of python interface working! (largely this pull request is to see if it passes travis :P)
update readme

There is no longer a separate configure step.
Added daemon-test
Add support for generic external tests or shell scripts; Add daemon test; Removenon-generic ezexample code (now supported in a nicer, generic way)
Add empty-set test (getting SEGV on bad builds so good to cover this)
Append test and . to PATH so shell scripts are found more easily
PATH fixes (so travis is ok with daemon-test)
Make sure we find vw first
Still failing in travis, but now with status 1. Make sure daemon is ready.
