boolean fields - return icons

[Ferdinand]

wish

pls instead of true and false we need a nationalized conversion function

true - YES
false - NO
null - empty

[sraps (Alistek) (erpsraps)]

There could be several possible variants:
0) displayed as they are;
1) "Yes" | "No" | "" - (can be translated);
2) "Y" | "N" | "" - (can be translated);
3) "+" | "-" | "";
4) "[ + ]" | "[ - ]" | "[ ]";

Some other function could return check-box typefaces from font...

Any other suggestions

As temporary workaround "if" directives can be used.

I agree with temporary workaround
nevertheless I think that the report coding becomes crowded using to many if's, hence please add as many functions as possible and meaningfull to ExtraFunctions.py to make coding easy and comfortable. (especially the empty image issue)
