#21 Menu Page Group listing fix for EMBOSS 6.4

[Andrew Neuschwander]

There is a logic bug in the _menu_html() subroutine that is triggered iff
the first group of applications only has one application. EMBOSS 6.4 has
this group/application configuration. On line 317 in
lib/EMBOSS/GUI/XHTML.pm (inside the _menu_html() subroutine change the line
from

if (@{$entries[0]} > 2) {# entries are groups...

to
if (ref($entries[0][1]) eq "ARRAY") { # entries are groups...

This will cause group listing to be detected correctly. I'll attatch a diff
-u output for easy patching. This has been tested on Fedora 17 and CentOS
6.3.

This bug also exists in more recent EMBOSS versions.
The patch fixed the issue in EMBOSS 6.5.7 on OpenSUSE 12.2.
Thanks!
