In 2d7e6179 (wendelin.core: Add part/recipe how to build it from git
repository) I've added wendelin.core-dev part, but forgot to set :egg
variable inside it.

Hello web

Hello up there.

While studying how SlapOS works, I've turned helloworld example into real web-service.

New helloworld software-release was tested ok:

    - inside webrunner, and
    - instantiating in "raw" slapos locally under slapproxy.

Please apply and thanks beforehand,
Kirill

See merge request !2

Quoting @jerome:

    @kirr, we usually extends component/git/buildout.cfg and use
    ${git:location}/bin/git instead of git, in case git is not always in the
    path, especially in webrunner.

also use our own libraries more.
clean up rpy2 component.

because nodejs does not compile in testnode in webrunner

It is probably better to stop using grunt

This reverts commit 27fd1355.

Let's merge and switch wendelin development to master.

For now we only add components which should be orthogonal to the rest
and cannot break things. Yet master is a focal point for joint effort
and people can try wendelin work-in-progress.

* wendelin:
  wendelin.core: Add part/recipe how to build it from git repository
  components: wendelin-core -> wendelin.core
  Add Ipython and pandas python libraries.
  Add wendelin-core.
  Add msgpack-python library.

There is now

    wendelin.core       and
    wendelin.core-dev

parts.

wendelin.core just installs released egg from pypi, and
wendelin.core-dev installs it from latest git version.

A reminder how to use wendelin.core-dev instead of wendelin.core:

if your buildout.cfg

    [buildout]
        # directly or indirectly
        extends = ..../wendelin.core/buildout.cfg

then at tails, do

    [buildout]
        parts -= wendelin.core
        parts += wendelin.core-dev

This way wendelin.core will be fetched from git repository.

.core is part of the software name, and buildout allows dot inside a
name.
