First attempt at implementing an option for the parser to support case
insensitive keywords (e.g., "program", "PROGRAM", "Program" ... in
PL/0).
Added test cases for AutoEditStrategy and fixed a bug.
Merged functionality of StringParser into ResourceUtil.
Implemented new option caseInsensitiveKeywords to advise the parser to
accept keywords in any case constellation (e.g., "program", "PROGRAM",
"Program" etc. in Pascal).
Merge branch 'master' into caseinsensitivekeywords
Merge pull request #56 from chseidl/master
