* move common file-specific functionality out of IDF_Views_Source into new

Browse Source 
IDF_FileUtil and change all occurrences accordingly
* cache /etc/mime.types (or whatever is configured) per request in a static
variable in IDF_FileUtil
* always link directly to the download of attached files in the issues view
and place an additional "view" link only for those attachments which we
recognize as text with our weak criteria (closes issue 575)
