Subject: Put recently used engines in WB menu
X-Git-Url: http://winboard.nl/cgi-bin?p=xboard.git;a=commitdiff_plain;h=f4cc69edd466fda83f84629f40c086dd2a249616

Put recently used engines in WB menu

A new option -recentEngines specifies how many engines should be listed.
The list of nicknames is stored in the ettings file as -recentEngineList.
The engines are appended to the Engine menu.
