Core installer

[bragento]

I've added the magento-core package type with installation and update routines, allowing you to set up the whole project with composer.

Using either https://github.com/bragento/magento-core or http://packages.firegento.com (as soon as my pull request for the magento/core repo gets through) you can now require "magento/core" which has the "magento-core" compoyser package-type.

The added pre/post Install/Update routines for this package type allow for a fully automated Magento Installation and seamless Update processes.

1. Installation:
   • Require magento/core
   • If no magento-root-dir defined you are prompted to define one
   • If your magento-root-dir is missing, you are prompted if you want to have one created automatically
   • You can have your composer root file require any magento-module packages besides the core
   • During the installation the root-dir is emptied in order to bypass possible filesystem hickups with symlinks
   • After the core installation -- the magento-modules which may have been installed up to that point are redeployed with the configured deploy strategy -- the folder rights required by the Magento core are set (by default [app/etc, media, var])
2. Update:
   • While updating certain files and folders need to be persistent to guarantee a seamless upgrade without data loss (by default [app/etc/local.xml, media, var])
   • During the update process a tmp root dir is created where a fresh core is installed first
   • Afterwards the modules get redeployed there again
   • Finally the folder rights are set again
   • The persistent folders are moved into the updated core
   • The "var/cache" folder is cleared
   • You are prompted and get a final chance to check if any files in the original root dir need to be transferred to the updated root
   • The backup dir gets cleaned up

My first tests were very promising. Now I would like to involve the community to round things up.

@Flyingmana any chance to be merged? I find interesting

[Flyingmana]

will get merged, but need a bit time to test and refactor a few things

@Flyingmana : I find this interesting as well, however I would for the first version opinion against the automatic magento-dir creation and the automatic clean (removal) of the root directory. Just my 2 cents. Ping me if you like to test something.

please test if still everything works :+1:
