[orion-dev] Updates to Orion/Getting the source wiki page

[Anthony Hunter <anthonyh@xxxxxxxxxx>]

Hi Team,

I have made a few updates to http://wiki.eclipse.org/Orion/Getting_the_source.
I have been using this guide to self-host in an Eclipse IDE and it needs
a few tweaks. Correct me if I am wrong but this seems to be *the* guide
for setting up an Orion server development environment.

I have updated http://wiki.eclipse.org/Orion/Getting_the_source#Install_the_Eclipse_SDK
to reflect the comments in https://bugs.eclipse.org/bugs/show_bug.cgi?id=409440
.

I cleaned up the wording for Kepler
and the package name for the Eclipse Git Team Provider changed so fixed
that as well.

I also added to install the Eclipse
Web Developer Tools package. If you do not, by default Eclipse will open
CSS and _javascript_ files in an external editor, which is somewhat annoying.

I have updated http://wiki.eclipse.org/Orion/Getting_the_source#Clone_the_client_and_server_Git_repositories_into_Eclipse
to take advantage of the Git support in Eclipse and not make the user think
they need to install additional git tools.

I have updated http://wiki.eclipse.org/Orion/Getting_the_source#Specify_a_target_to_build_your_Orion_server
based on https://bugs.eclipse.org/bugs/show_bug.cgi?id=409770
. We can use this target and it includes all the source bundles. Using
an orion build as a target does not really work if you want to debug as
most of the source bundles are missing.

I left both of http://wiki.eclipse.org/Orion/Getting_the_source#Set_up_the_server_configuration_file
and http://wiki.eclipse.org/Orion/Getting_the_source#Run_the_Orion_server
mostly as is but did update the screenshot of the navigator for 3.0.

If there are any comments let me know.

Cheers...
Anthony
