Have added a new bool strict flag to the parsing functions, if the strict flag is set to false the parser will just skip lines with unknwon keywords, including pure garbage in the input. I.e. for a deck like: TABDIMS 1 1 1 / Crap - not a keyword at all -- Correctly formatted - unknown keyword IGNORED 0 1 / The parser will load the TABDIMS keyword correctly, and skip the rest.
