add support for list parameters

[anb0s]

For "clipboard" commands EasyShell already collects all selected resources. Then it executes variable expansion for each of them and copies this to one string and passes it to clipboard at the end.

We need some improvements here:

1. for all other commands it's not possible to do it
2. some commands (bash + git add etc.) need a list of converted resources that is resolved in the command itself

Proposed solution:

• we need new parameters or extension for support this case, e.g. append "list"
• for some tested commands (diff tools) we need indexed parameters -> acces list at index N, e.g. name it "index", related to #41 and #70
• the list elements have to be separated by delimiter that should be variable for user, e.g. "delimiter"

Just investigated the solution and it needs some major changes to the "action execution" handling --> moving to 2.2

Being able to pass a list of resources to a command, e.g. the files currently selected in the project explorer, is something I would very much like to see...

I will add it for next version...

That's great! Any plans when the next version will be available?

[anb0s]

I've no exact plans, but want to release it for Eclipse 2019-03 --> March 2019

I'm preparing new test build for this weekend and will create issue with testing request / help needed like #169

All fixed issues will be referenced there, so if this one is also solved please help with testing ;)

I'll be happy test
