Performance improvements

Using cfsavecontent in renderArraySection as it's faster according to tests.

Creating java regex Pattern object only once

Replace partials into template at start to simplify the process.

I made these changes because I was finding that looping over arrays and rendering partials was particularly slow. The following is the test code I was using to compare performance to old and new:

<cfset mypartial="this is the iteration number {{element}}">
<cfset template="This is a test template looping over a partial with {{count}} items in it {{##results}}{{>mypartial}}{{/results}}">

<cfset newMustache=new Mustache(
            partials={
                "mypartial"=mypartial
            }) />

<cfset oldMustache=new Mustache2(
            partials={
                "mypartial"=mypartial
            }) />

<cfset content={
                "count"=1000,
                "results"=[]
                    }>

<cfloop from="1" to="#content.count#" index="i">
    <cfset arrayAppend(content.results,{
                    "element"=i
                }) />
</cfloop>

<cftimer label="newMustache">
    <cfset result=newMustache.render(template,content)>
</cftimer>
<cftimer label="oldMustache">
    <cfset result2=oldMustache.render(template,content)>
</cftimer>

Times with newMustache are at least 4x as fast on my machine (Mac with CF9). Drops from 900ms to 200ms. Sometimes oldMustache was even 1500ms or more.
