[bionic] dokuwiki incompatible with php7.2

[Clemens Drüe]

Dokuwiki 20160626 has become incompatible with php >=7.1.
The Error causes all pages generated to lack formatting completely.

Solutions:
* change "importDir[]" into "importDir" in lines 169 and 172 of /usr/share/dokuwiki/lib/exe/css.php
* upgrade Dokuwiki to current upstream version

Thanks Clemens, that saved me some head scratching. One minor correction to your first solution - the second change of "importDir[]" to "importDir" is on line 173, not 172.

Thanks.
