Change to the Official Library Spec for Pattern Naming

[Orion Pobursky]

Based on a discussion on the PT forum, I'd like to proposed the following change to the Official Library Spec.

https://www.ldraw.org/article/512.html#pattern_desc
(changes in bold)

The description of a patterned part should in the following format:
<base part description> with <pattern description> Pattern

Where:

•     <base part description> is the description of the non-patterned version of the part. Note: For parts with mold variants (e.g. tiles with or without groove), the additional qualifier for the mold is only required if the same pattern is printed on more than one variation. Example: "Minifig Head with Solid Stud with ... Pattern" can be shortened to "Minifig Head with ... Pattern" if the pattern being modeled only appears on the "Solid Stud" variation.
  
•     <pattern description> is a reasonably detailed description of the pattern. If unsure, use of the description on other inventory websites is encouraged.
