Poincare/Python translation feature, and remove the cap on the length of
text being imported into the simulator.

Add methods to interface Epsilon's clipboard with the system's when
running a simulator.
Note that the clipboard still uses a buffer located in the
Escher::Clipboard class, as some features require a buffer to execute
computations on the clipboard's content.

Fixed issues due to copy/paste of empty formulas. When pasted, empty
formulas are now recognized by the parser and apear with the
correct layout
Without this process, copying an empty integral then pasting it gives :
int((), x, (), ()) instead of drawing an empty integral

When a formula is pasted in a script or in the shell, some symbols are
replaced by their equivalent in python :
x turns into *
^ turns into **
√ turns into sqrt
etc
