This fixes an exploit where you could alter the 'Content-Type' of the
request and bypass the case-sensitive check 'strstr'. For example,
setting it to 'application/x-www-FORM-urlencoded'. However, changing
this to use 'stristr' was also not an acceptable approach as you
could also bypass it by setting the value to 'multipart/form-data'.
* Define consumer profile member variable for ToolConsumer class
* Added context type property for Context class
* Set context type if 'context_type' parameter was submitted through POST
