Add new directory structure. Tags will contain current and past releases, and stable will contain any bug fixes to the current stable release so users won't have to get the potentially broken trunk build to fix a screwup in stable.

Trunk updated to 0.9

+/**
+ * Initiates a counter that is incremented every time you call it
+ * <pre>
+ * * name : the counter name, define it if you want to have multiple concurrent counters
+ * * start : the start value, if it's set, it will reset the counter to this value, defaults to 1
+ * * skip : the value to add to the counter at each call, defaults to 1
+ * * direction : "up" (default) or "down" to define whether the counter increments or decrements
+ * * print : if false, the counter will not output the current count, defaults to true
+ * * assign : if set, the counter is saved into the given variable and does not output anything, overriding the print parameter
