Issue #1234140 by arlinsundbulte, Change terminology in user-facing text from 'From/To Date' to 'Start/End Date'.

Issue #1150462, Put length limit on content type names created by Date Tools so block delta won't overflow the allowed size.

#983330 Remove deprecated use of views_object_cache_clear and replace it with ctools_object_cache_clear.

#963844 Fix the date filter and argument so they will show up both under the 'Date' group and as 'Content' fields. Also a few tweaks to Date Wizard.

#545466 Fix bid placeholder in date wizard, patch by colinsherry. Also add date type change code to D7 branch, that still needs work.

Refactor Date Tools and the Date Wizard. It will create date fields, but fails to create content types to put them on, so more work still needed.
