My Xed Vala Plugins

[tudo75]

Hi,
I'd like to promote my porting of some Gedit plugins to Xed (at least with some modifications and little improvements):

https://github.com/tudo75/xed-restore-tabs-plugin
https://github.com/tudo75/xed-plantuml-plugin
https://github.com/tudo75/xed-terminal-plugin
https://github.com/tudo75/xed-sessionsaver-plugin
https://github.com/tudo75/xed-codecomment-plugin

Do you want to create a PR for this? Please describe what these plugins do, give a few screenshots etc. It's helpful to pay attention to this issue.
