Subject: Implement champlain_selection_layer_select_all
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8c9c621a7744a5a00a6d68c83edf16e7cde00170;p=libchamplain

Implement champlain_selection_layer_select_all

This implementation will only work when the layer selection mode is set to
multiple. This is because it seems strange to select more than one marker if
the selection mode is set to single.
