Cache key trimming

I noticed an inconsistency in the ColdBox 2.6.3 CacheManager and I
wasn't sure if it was known/desired.

The objectKey is trimmed before being used in the set method, but is
not trimmed on the get, clearKey, or lookup method (and a couple
others).

That means code like this will return unexpected results:

<cfset keyName = "foobar "><!--- Notice the trailing space --->
<cfset variables.cacheManager.set(keyName,"test",10)>
#variables.cacheManager.lookup(keyName)#<br>
#variables.cacheManager.get(keyName)#

Output:
false
_NOTFOUND_

I briefly looked through the docs and API and couldn't find any
references to what a valid objectKey was allowed to be. Even if
leading or trailing spaces are not permissible, it seems that the
cacheManager shuold be consistent and always trim or never trim
incoming objectKeys.
