Changed: Some changed to be considered if useful.

checking for media folder on development server first before create folder in repos. I have added libraries support to the project (get_library) and also put the extension in its folder e.g. com_xxx in compoents/com_xxxx. For this reason the project support of multiple components, modules and plugins as well as library.

I am not an expert in Git and well as PHING, if it is useful you can merge it. 

Sorry for my poor English. Thanks
