Fix code review issues: use with-current-buffer, fix documentation, improve property detection

Browse Source 
- Use with-current-buffer instead of set-buffer in tp-forward and tp-backward
- Fix tp-search documentation to correctly describe return type as list of (START END VALUE)
- Improve property detection in tp-search to handle falsy property values (0, nil, empty string)
