Add documentation of the new hex output formats. Thanks to text contributed by Tom LeMense, the manual now includes documentation of the hex formats he contributed. This also includes some updated text on the ORG directive. Only minor editorial changes vary the text from Tom's original.

80 >This ASCII format consists of a series of CR+LF terminated "records" of ASCII
81 text. Each record has the following structure: a start-of-record character
82 "S", an ASCII record type digit (0-9), a two-digit ASCII hex byte count, a
83 four-digit ASCII hex address, an optional sequence of two-digit ASCII hex data
84 values, and a two-digit ASCII hex checksum. The LW tool chain issues only S0,
85 S1, S5 and S9 record types. S1 records are limited to maximum of 16 data bytes
86 in length, and paragraph alignment of addresses is favored. The address
87 sequence of the S-Records directly follows that of the source file; multiple
88 ORG directives in the source code may result in out-of-sequence addresses in
89 the S-Record output. </P
90 ><P
91 >Motorola S-Record format is a standard ASCII format accepted by most memory
92 device programming equipment. It is particularly useful when the assembled
93 code output is destined to reside within an EPROM or Flash memory device,
94 for example.</P

96 >LWASM can output this format since version 4.10.</P
