autoconf: Added the -Wunused-but-set-variable to the default compile to help avoid commiting more unused variable but set value.  Please report if you do have problem with it.

mod_callcenter: Quick changes to try to make it more multi platform friendly.  Still need to find the best way to convert a string to time_t that is multi platform.

mod_callcenter: Changes lot of log file to include the uuid of the member.  Also added a bunch of debug log entry to help debug an issue

switch_ivr/xml: Change the structure of the phrases/language system. Previously it was fxml->phrases->macros->language->macro.  Changed it so fxml->languages->language->phrases->macros->macro
You can have sub macros <macros name="voicemail"><macro ...> and allow you to call it login@voicemail.
Change the sound-path to sound-prefix to make it constistant with the rest of freeswitch.
Also allow to set a sound-prefix to a macros, so you can override it for a specific file set.
You can set say-modules="en" or whatever in the <language section to define that say module to use.

adding fix that was reported on the mailing list and thoughtlessly left there to rot despite my begging them to open a JIRA
