First commit after merging search_files with search_attachments. A bit messy, but mostly functional. Still needs another iteration of testing and code review.

Added filename to text string being indexed. now at the begining of the indexed string ther is 'file name: '.  .', text: '. . This is a personal request from jbrauer.

removed a line checking the drupal file sstem path, since we dont use that we don't need to check it

trying to resolve issue [#250086], we need some more feedback while installing so we made some changes in the hook_install() displaying errors and recording errors to the log

search_files_install() not sets the variable search_cron_limit to 10 to prevent cron timeout continuously

fixed type in directory_add_submit function, plus added text to indicate to user that it may take up to one day to start indexing

edits for the helper apps wasn't saving, I was using the form_values['values'] array which aparrently is the default values so I switched to form_values['clicked_button']['#post'] array, this works

when after we fail to index the file 5 times we set a watchdog message, change the type from emergency to error

instead of listing the directories once per cron run and putting the files in the search_files_files table, only do it once per day

implemented tracking how many times indexing attempts are made, attempts are stopped after maximum of 5

I had it relying on a funcition in another module that was recently disabled, I forgot to update the funciton name to use the fnstion in this module

fixes to hook_schema(), mainly I forgot to add the fields in the  tables, and the whole thing was commented out
