Add support for MantisBT 1.3.x

[Mondane]

I just upgraded my MantisBT from 1.2.19 to 1.3.2 and it turns out that agileMantis isn't loaded. Could you add support for the 1.3.x core?

Managed to get it running by changing this line in plugins/agileMantis/agileMantis.php

                $this->requires = array( "MantisCore" => "1.2.5" );

to

                $this->requires = array( "MantisCore" => "1.3.0" );

Now testing if all functionality works as expected.

Found out the plugin images weren't showing caused by a new .htaccess in the /plugins folder with these contents:

order allow,deny
deny from all

For now, I've fixed it using this contents:

order deny,allow
deny from all
allow from <your ip>

Styling is not fully applied due to this error:

Refused to apply inline style because it violates the following Content Security Policy directive: "style-src 'self'". Either the 'unsafe-inline' keyword, a hash ('sha256-3s4EdbIRodzowhevjFvOA9X3QjIFN+dhtZodnlGlhQM='), or a nonce ('nonce-...') is required to enable inline execution.

This is in Google Chrome 54.0.2840.59 (64-bit)

It seems, because of this, styling breaks on several agileMantis pages.

I've found similar issue with edit_sprint.php, then I've created edit_sprint.js.
