+ Plugins: Added {a} to build 'a' html tags

CHANGELOG

 [2008--] 0.9.2
++ Plugins: Added {a} to build 'a' html tags
++ Plugins: Added {tif} that acts as a ternary if / allows you to use a ternary
+  operator inside it
+* The compiler now allows \r, \n and \t to be parameter splitters as well as
+  "," and " ". You can therefore make complex function calls on multiple lines
 * Converted most of the code to follow PEAR Coding Standards, hopefully this
   didn't break anything that the tests missed
