; Function Name:    _StringEncrypt()
; Description:      RC4 Based string encryption
; Parameter(s):     $i_Encrypt - 1 to encrypt, 0 to decrypt
;                   $s_EncryptText - string to encrypt
;                   $s_EncryptPassword - string to use as an encryption password
;                   $i_EncryptLevel - integer to use as number of times to encrypt string
; Requirement(s):   None
; Return Value(s):  On Success - Returns the string encrypted (blank) times with (blank) password
;                   On Failure - Returns a blank string and sets @error = 1
