# Implementation:
# 1 - set WEB rereadicons
# 2 - define rc1 remotecontrol    (defines fresh remotecontrol, has no keys defined yet)
# 3a- get rc1 layout              (display list of available "keybiard"-layouts)
# 3 - set rc1 layout samsung      (assigns standard-key-layout for e.g. samsungTV)
# 4 - set rc1 makeweblink         (creates a weblink weblink_rc1)
# 4a- for testing: attr rc1 room TestRemote , attr weblink_rc1 room TestRemote
# 5 - set rc1 makenotify <executingDevice> (creates a notify of the form: define notify_rc1 notify rc1 set <executingDevice> $EVENT)
#
# Published June 23, 2013
# bugfix "use strict" upon foreign makenotify - June 24, 2013
# converted to UNIX-LF - June 25, 2013
# fixed minor html-bug - June 26, 2013
# added css-tags rc_body and rc_button - June 27, 2013
# deleted leading \n at beginning of html-code - June 30, 2013
# fhemweb-detailscreen of remotecontrol now displays a preview, added htmlNoTable for RC_attr2html(), added RC_summaryFn incl attr rc_devStateIcon

  Displays a graphical remote control. Buttons (=icons) can be chosen and arranged. Predefined layouts are available for e.g. Samsung-TV or iTunes.
  Any buttonclick can be forwarded to the actual fhem-device. For further explanation, please check the <a href="http://www.fhemwiki.de/wiki/Remotecontrol">Wiki-Entry</a>.<br>

    <code>layout &lt;layoutname&gt;</code> assigns a predefined layout to rowXX-attributes</li>
    <li><code>set &lt;rc-name&gt; makeweblink [&lt;name&gt;]</code><br>

        <code>attr rc1 row00 VOLUP </code><br>
