[mouse] Create or delete ~/.elinks/mouse.lock file while changing ui.mouse_disable option. Refs #137
There is no good way to inform slave elinks instances about options. So, for mouse there is a workaround. Note, If you set ui.mouse_disable = 1 in elinks.conf manually, to get effect on 2nd ELinks instance, you must also touch ~/.elinks/mouse.lock . Changes via option manager delete or create this file automatically.
