Make ECMAScript browser scripting configurable

Either set CONFIG_SM_SCRIPTING in features.conf or pass to ./configure the
option --disable-sm-scripting. Now scripting is also enabled when needed
and not only if some other scripting backend is enabled.

Remove some remnants of SEE scripting backend.

+### ECMAScript (JavaScript) Browser Scripting
+#
+# By enabling this feature, certain parts of ELinks, such as the goto URL
+# dialog, may be extended using ECMAScript (aka. JavaScript) scripts. This can
+# be useful to optimise your usage of ELinks.
+#
+# For example you can define shortcuts (or abbreviations) for URLs of sites you
+# often visit by having a goto URL hook expand them. This can also be achieved
+# with the URI rewrite feature (CONFIG_URI_REWRITE), however it is not as
+# powerful as doing it with scripting.
