Appends one path to the end of another
_WinAPI_PathAppend ( $sFilePath, $sMore )
|$sFilePath||The string to which the path is appended.|
|$sMore||The path to be appended.|
This function automatically inserts a backslash between the two strings, if one is not already present.
The first path cannot begin with "..\\" or ".\\" to produce a relative path string. If present, those periods are
stripped from the output string. For example, appending "path3" to "..\\path1\\path2" results in an output
of "\path1\path2\path3" rather than "..\path1\path2\path3".
