#17 Formatted output indent size

[Nick Holgate]

Here's a small patch to V2.3.3 that allows the amount of
indent to be specified when using the Print() formatted
output function. Simply call the SetTabSize() function on
the document to set the size of each level of indent
before calling the Print() or SaveFile() functions. A
parameter of zero to SetTabSize() will cause one tab
character per level of indent to be ouput. A positive
integer value will cause the indent to be that number of
space characters per level of indent. If SetTabSize() is
not called the default tabsize of 4 will apply.
