Apple icon files missing

[mrvdb]

templates/user/include/header.tmpl refers to three icon files which are not in the repository:

/img/touch-icon-152.png
/img/touch-icon-167.png
/img/touch-icon-180.png

[mrvdb]

Not sure if you want to use the same icons, but pull request #78 has the write.as/img/touch* files

Fixed in #78
