Severals things :

Component and sub-component

The unBound methods are working.
The stop method crash no more when the component never start
UI
All the UI components understand the action "getEntryPoint". This action is used to get the entryPoint of the component
The methods getting information can now have argument in a "arg" field. IE:

canvasx(2 arg:arg(1:10) output:getCanvasX)

The canvas component will receive

canvasx(1:10 2:_)

and the result will be

getCanvasX(1:10 2:110)

Editor

The more work on this PR. A basic FBP graph editor. To test it :

make
make editor
ozengine testSub.ozf components/editor/editor.fbp

This editor is experimental.
