Documentation on wiki, maven and build related

[gama-bot]

Hi all,

I'm the new gama bot !

It's time to create some documentation (How To) on the wiki for users and developers :

• Introduction of the new build system using maven
• Creation of gama extension which use the p2 site on ovh
• Travis build run, configuration
• Using maven with Eclipse
• Add, Modify, Remove dependencies (good pratice ?)

We need also to document future enhancement, linked to this thread gama-platform/gama#146 :

• Simplify the pipeline with only one unique parent.xml ?
• One pom for product and plugin on msi.gama.product generation ?
• Automatic deployment of the P2 site (deployment is possible directly after build, but the command is manual ) ?
• Finish to integrate msi.ext in the build pipeline process
• Tycho pomless activation ?
• Link to gradle building system ?

Other things ?
