Mismatch between Name length

Databases store 50 chars for users name, but login form enable only 20
and client creation enable only 10.
Updated forms to enable 30 chars client name.
Removed double / in html content for pathes

all pathes have a double '//' betwenn zpanelx and subdir. in example :
<script type="text/javascript"
src="etc/styles/zpanelx/inc/jquery.min.js"></script>
was
<script type="text/javascript"
src="etc/styles/zpanelx//inc/jquery.min.js"></script>
