Adding getUpText() and isUpText()

[KeepBotting]

Adds some OCR functions to SRL-6 using SimpleOCR. These functions will read UpText, similar to the existing functions that read mouse-over text.

Why do you choose to remove everything that's not a character or a decimal from the result of GetUpText. Would not the raw output be better?

Looks good, would be nice if you could answer my one question tho.
Gonna give it some test-runs.

Update:
Tolerance could perhaps be tweaked a small amount, the shadow tolerance in particular, could be increased, didn't change much, but in worse cases it seemed to help, as the shadow is rather gray when facing very bright background. filter: TCompareRules := [-1, 85, true, 60];

I also noted that the space width is ~5pixels, rather than 4 which is default.

begin
  ocr.Init(FontPath + 'UpCharsEx');
  ocr.FontData.SpaceWidth := 5;
end;

Agree, isn't a '-' etc also quite useful?

@warpie I decided it would be a good idea to sanitize the output if OCR ever bugged out and gave crazy output. I was experimenting with rs_GetUpText() and it kept giving me crazy output full of symbols and garbage characters so I guess I got kind of paranoid :P

You're right though, there's no real reason to do it. I'll also update the shadow tolerance and add the space width.

@MerlijnWajer Yeah, it is. Along with '/' as well. I see now that stripping the output was probably a bad idea. I'll change it.

Edit: Pushed. Thanks for the feedback :)
