Added a simple "TextEditor" in the graph, for a plan mode.

Added a simple TextEditor in the graph for the 'Dive Plan' mode,
this text editor is very simple, so the user can double click on
'depth' or 'duration' to set the depth or duration of the dive.
Since this was a test, only 'duration' was done, and I'll add
duration on the next commit.
