Patch 1 to Browse release of this morning.

[Peter da Silva]

This adds a new command to browse, 's' loads a saved macro file. The
format of the macro file is also slightly changed. This is based on the
version I posted this morning, but should work as applied to most
versions of browse, since I haven't changed this code recently. Have
fun!
