This reverts commit a94b738407.
It turns out that change stops the SHELL function returning the
child exit code, which is worse than having zombie processes.
This change adds the Program Files and Program Files (x86) folder specifications to the `_DIR$()` function.
`Print _Dir$("program files")
Print _Dir$("program files x86")`
Where the previous bug would only return the console's image size when an image was passed, the new bug made it only ever return 80 for `_Width` and 25 for `_Height` when it should be returning the console's image size if there is no value passed and it is the `_Source`, which it is if we are in a `$Console:Only`.
Here is a code block that demonstrates the bug being fixed:
```Option _Explicit
$Console
Screen _NewImage(640, 480, 32)
_Dest _Console
Width 120, 5
_Dest 0
Print "Hello world"
Print _DesktopWidth, _DesktopHeight
Dim As Long i: i = _NewImage(1280, 720, 32)
Print _Width, _Height
Print _Width(0), _Height(0)
Print _Width(_Console), _Height(_Console)```
When opening a file for random access, if the LEN is not supplied, it defaults the length correctly, but does not allocate the buffer correctly. The code should reference the record_length in the file struct.
The processing for MKDMBF$ fails for numbers smaller than 1. Basic cause is the check for exponent overflow is incorrect. Changed code to correctly check for exponent overflow

Changes in lines 15798-15853: When printing text to the screen, carriage returns in the text are ignored. In sub_file_print, the code for printing to the screen is modified to honor carriage returns.
Fixes a bug that would make QB64 return the incorrect size monitor/desktop size when the resolution is scaled. Also, the last fix I added that set `_Source` to `_Console` automatically caused an issue with `_Width` and `_Height`, causing them to return only the console's image dimensions rather than the image that is passed.
