CRM-1718 Advanced Search - Change Log Search is Broken

Search on Change Log by date range isn't doing the right thing.

Example: on http://dgg.devel.civicrm.org

• Advanced Search - Change Log: Modified Between Mar 19 2007 - Mar 21 2007
• Qill:
  Found 2 contacts
• Modified Date - greater than "March 19th, 2007" ... AND ...
• Modified Date - less than "March 21st, 2007"

However, looking at Change Log details for one of the two (cid=108), last change was Mar 11, 2007

Queried civicrm_log - and found that the problem is as follows:

• Code query is returning 2 records in civicrm_log
  ------------------------------------------------------------------+

  id

  entity_table

  entity_id

  data

  modified_id

  modified_date

  ------------------------------------------------------------------+

  163	civicrm_individual	108	NULL	102	2007-03-20 09:58:53
  162	civicrm_contact	135	NULL	102	2007-03-20 09:58:53

... one for civ_individual record and one for civ_contact record. It should be ignoring the civ_indiv record - but instead is evaluating that as a civicrm_contact.id

Separately, I would recommend that the query be changed to ">=" the "from" date (rather than ">"), and "<= 'yyyymmdd 23:59'" on the end range date. So if I want to find things modified on a given day I can put in that single date as From and To.
