- Added support for specifying a char literal for various types of instruction

- Fixed a bug preventing the usage of negative float/double literals
- Fixed escape sequences in character literals
- Added source file name to parser error messages
- Fixed an issue where the parser would exit without an error message, when it encountered a bad "top level" token (in the smali_file rule)
- Fixed an issue that prevented the usage of non long/double literals with the the const-wide instruction
- Fixed an issue with the invoke-static/range, where it wouldn't calculate the number of parameter registers correctly, and would erroneously generate an error message
