Ruby Improvements

[Matt666]

Hi !
Having access to all entities via "ruby" would be a big improvement for SU... For the moment, the dimensions and texts (for example) are inaccessible to ruby. impossible to modify these entities.

Another nice improvement would be able to use the existing commands, as the "Command" function in Autocad-Lisp. For example, to create a dimension entity by giving three points... Also be able to make a "pause" in the command, etc...
