Contextual links for front end editing not showing.

I changed this issue to bug report from support request. Thanks stiffler for your mention.

First of all stiffler, i would like to thank you for your feedback. You are absolutely right with your mention. This issue caused from the code in block.tpl.php file. Just replace all block.tpl.php content

<div id="block-<?php print $block->module .'-'. $block->delta; ?>" class="clear-block block block-<?php print $block->module ?>">
<?php if (!empty($block->subject)): ?>
<h2><?php print $block->subject ?></h2>
<?php endif;?>
<div class="content"><?php print $content ?></div>
</div>

with the following code

<div id="<?php print $block_html_id; ?>" class="<?php print $classes; ?>"<?php print $attributes; ?>>

<?php print render($title_prefix); ?>
<?php if ($block->subject): ?>
<h2<?php print $title_attributes; ?>><?php print $block->subject ?></h2>
<?php endif;?>
<?php print render($title_suffix); ?>

<div class="content"<?php print $content_attributes; ?>>
<?php print $content ?>
</div>
</div>

All changes are committed and will be included in next Bluemasters release 7.x-1.3. Thank you for understanding.
