Conf modification

• $WIKI_HOME/conf/mime.conf defines the types of files that can be uploaded.
• To change the types of files that can be uploaded, create $WIKI_HOME/conf/mime.local.conf and edit the file accordingly.
• For example, to allow upload of .fasta file, add the following lines to $WIKI_HOME/conf/mime.local.conf:

# enable fasta file
fasta	 text/plain
