Changes

Fixed link to Rule Table Repository in Help > Online Archives.
Fixed paste bug that prevented rule from being changed even if universe was empty.
Updated the Life Lexicon to release 27.

Golly has a new algorithm that supports the Larger than Life family of rules.
Added support for MAP rules to QuickLife, HashLife and Generations.
QuickLife and HashLife now support non-totalistic rules. A number of interesting examples can be found in the new Patterns/Non-Totalistic folder.
The Generations algorithm now supports Hex, Von Neumann and non-totalistic Moore neighborhoods.
The Life Lexicon has had a major update.
The Banks, Codd, Devore, and JvN folders have moved into a new top-level "Self-Rep" folder, to emphasize their common focus on self-replication.
Rendering speed is faster in most cases.
Files with extensions .colors or .icons are no longer supported.
The Fit button will fit the paste image in the viewport if the current pattern is empty.
The action menu has a new Fit item that will fit the current selection in the viewport.
Double-tapping the paste image now stops generating (the same as tapping the Paste button).
Fixed an undo/reset bug that could occur if there was a rule change at the starting generation.
Fixed minor problems with status bar messages.
Major reorganization of source code so that the iOS and Android versions of Golly can share common code.
This version requires iOS 8.0 or later.

This version introduces a new rule format. A file in the new format has a .rule extension and contains all the information about the rule: its name, description, table/tree data, and any color/icon information. More details can be found here.
The RuleTable and RuleTree algorithms have been replaced by a new algorithm called RuleLoader.
If the Paste button sees clipboard text starting with "@RULE rulename" then it will save the text as Documents/Rules/rulename.rule and switch to that rule.
When the Rule dialog is switched to the RuleLoader algorithm it will display links to all the .rule files in Documents/Rules/ and to the supplied .rule files. Any deprecated files (.table or .tree or .colors or .icons) are automatically converted to .rule files and then deleted.
Icons can be displayed at scales 1:8, 1:16 and 1:32 by turning on the "Show icons" option in either the Settings tab or the Pattern tab's state picker window.
Fixed a bug that could cause the Undo/Redo buttons to be incorrectly enabled/disabled after tapping STOP.
The Open tab has READ and EDIT links that let you display or change the contents of pattern files. Only files stored in the Documents folder can be edited.
After tapping on a DELETE link you now get a warning dialog asking if you really want to delete the corresponding file.
The size of text in the Help tab has been increased.
Added support for file sharing using iTunes. More details here.
