lib/table.run: use new local.run instead of defining $bin_dir, etc. itself

lib/util.run: echo_export (): run the export builtin using `builtin` to avoid recursively calling any export alias or function defined by the user (e.g. `alias export=echo_export`. this causes util.run to be idempotent, such that it can be included multiple times without causing problems due to the redefinition of functions, vars, etc.

added lib/local.run, which links to locally-available resources such as $bin_dir

lib/table.run: added mysql (), mysql_ANSI ()

added web/links/index.htm containing Firefox bookmarks exported to HTML. CSS style information has been added to fix default HTML tag formatting, improve readability, and handle the Firefox bookmarks format. <dd> tags have been manually closed where HTML would not auto-close them properly. note that these changes must be reapplied each time the bookmarks file is reexported (`svn di` will show the changes to make).

lib/table.run: run mk_esc_name for $schema, $table

lib/table.run: added esc_name (), mk_esc_name ()

lib/util.run: added set_var ()

bugfix: lib/util.run: run_args_cmd (): `set --`: need to use eval so that the output of reverse is interpreted as escaped args rather than split using $IFS

bugfix: lib/util.run: run_args_cmd (): BASH_ARGV is stored in reverse order, so it needs to be reversed to be usable as $@
