CodeSnip Old Code (SVN)

Renamed UActiveText, UActiveTextHTML, UActiveTextRTF & UActiveTextValidator units into ActiveText namespace as UMain, UHTMLRenderer, URTFRenderer and UValidator respectively.
Updated all using units as necessary.

Changed TREMLWriter to write a newline after closing block level REML tags.

Modified TTaggedTextLexer to emit only first of any sequence of white space characters. Any intervening tags are ignored for this purpose so that "x <em> y </em> x" is parsed as "x <em>y </em>x". A side effect is that a text token with an empty string can be returned.

Changed TREMLReader.Parse to ignore empty text tokens received from lexer: no active text element is generated for empty string.

Fixed problem with REML parsing where nested block level tags in REML, such as <p>...<p>...</p>...</p> were being permitted.
Required new TActiveTextActionElemKinds set type in UActiveText unit.

NOTE: This fix may cause exceptions when loading any old REML code when block level tags are nested. All main database is OK, but some user defined snippets could be affected and their extra information will be lost.

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

Changed data type of IsCompound fields and flags in UTaggedTextLexer unit from WordBool to Boolean and updated calling code as necessary.

* Converted TREMLTags and TREMLEntities into completely static classes that use class vars and class constructors etc.
* Removed TREMLInfo class that handled previous non-static versions of TREMLTags and TREMLEntities and modified code that called TREMLInfo to call TREMLTags and TREMLEntities directly.
* Tweaked comments a little.

* Modified EActiveTextParserError exception to descend from EValidation.
* Changed TREMLReader.Parse method to map ensure that all raised EActiveTextParserError exceptions get a copy of the selection information stored in handled ETaggedTextLexer exceptions.

Removed unused EREMLEntities exception class.
