Add jump plugin, which allows you to easily jump around the file system

plugins/jump/jump.plugin.zsh

+# Easily jump around the file system by manually adding marks
+# marks are stored as symbolic links in the directory $MARKPATH (default $HOME/.marks)
+#
+# jump FOO: jump to a mark named FOO
+# mark FOO: create a mark named FOO
+# unmark FOO: delete a mark
+# marks: lists all marks
+#
+export MARKPATH=$HOME/.marks
