* make constant.d auto generate from .dd files (fix#428)
* added isDeprecated to constants.d
* add isDeprecated to expected keywords in traits test
* make traits message BARELY FIT into the response buffer
because who wants to increase the message buffer anyway? I certainly don't and this seems like a much better solution long term /s
* undo apply dfmt on constants.d
* use startsWith & canFind with multiple needles
* made completion have dynamic ddoc as input
* Remove debug pragma msg from constants.d
* Move message buffer to heap, increase size to 1MB
* made traits & pragma ddoc generation separate tool
