Adding additional documentation on Issue 575 and Vagrant behavior changes since 1.3.0,

[GH-575]: Users are now told not to install VirtualBox 4.3.0 or higher.

Other edits:
The documentation changes describe the changes in behavior in the ``vagrant up`` and ``vagrant reload`` commands since Vagrant 1.3.0, as per the Vagrant changelog (https://github.com/mitchellh/vagrant/blob/master/CHANGELOG.md#130-september-5-2013):
* Both commands no longer automatically run the provisioning script when used.
* The --no-provision option is no longer needed.
* Conversely, the --provision option is used to force Vagrant to run the provisioning script.

Some typos were fixed in the installation-makahiki-vagrant-eclipse.rst file. It now specifies that a Python file must be opened for the syntax completion demonstration to work.
