CodeSnip Old Code (SVN)

Added new stored selection search to supported search types, along with a new icon resource for the search.

NOTE: Much duplication of code: implementation of new search largely replicates existing selection search and needs cleaning up.

Reverted all changes made to USearch in r1883, except for copyright date and TODO item. This was done because revised implementation of nested searches in UQuery (see r1889) makes these changes to USearch unnecessary.

Added new TCompoundSearch search that applies two searches consecutively. These searches can themselves be compounded to give chains of three or more searches.
Also added new factory method to create a TCompilerSearch instance for two given searches.

Changed TTextSearchCriteria to store selected snippets in a ISnippetIDList object instead of TSnippetList.
This fixes long standing bug #2868707

Standardised svn:mime-type properties to "text/pascal" and svn:eol-style to "native"

Reintegrated v4-dev branch into trunk.
Trunk now contains v4 development tree

* Moved all units directly concerned with supporting installed compilers into the new "Compilers" namespace. Some units were further renamed.
* Revised using units to use the new names.

* Moved IsHexDigit routine from UUnicodeHelper unit to UUtils.
* Removed from UUnicodeHelper unit all character test and case conversion routines that mapped directly onto methods of TCharacter or to CharInSet in SysUtils unit.
* Modified units that used these routines to use replacements in Characters, SysUtils and UUtils units.

Updated copyright date where required on some files modified in 2010.

Merged delphi2010-port branch back into trunk.
