error check missing parts + remove tplTemplate()

removed all references to 'template' - changed to hATS where relevant to
avoid confusion over terminology
added 'missing part' error checking
added STOP_ON_ERROR variable to exit instead of show friendly error
message when missing part found
removed setTemplate()
added setDefaults()
removed hAts_DEBUG declaration
minor _tplDebug() changes
v2.0 beta

removed $in_parts_subdir parameters
users should now tplSet('IN_PARTS_SUBDIR', FALSE) to *prevent* hATS
looking in Parts sub-folders for resource files (css,, js, image).

see CHANGELOG for list of functions with parameter changes (pretty much
all Stylesheet, Javascript and Image functions).
flagResponse() update & example page message
v2.1.0
