Proposal to transmute Rule 105.

Rule 105 is an Initial Set immutable rule. I propose to make it mutable, and in accordance with Rule 108 ¶ 2, Rule 105 will be re-numbered Rule 302. 

Rule 302 will support greater flexibility in future rule making about the pace of play and role of individual players.

[edit for clarity: I am proposing a change to Rule 105, not 102 as originally proposed here. The edit to the rules was correctly for Rule 105 -- see aee11aeaaac0e9549f4eefbd1e645a7b562500ff ]
