Create backup in 'try' directives

[snaulX]

On this moment, compiler, when meets try directive makes tryDirective = true. In endtry directive, compiler makes tryDirective = false and just clear errors but the compiled code remains. Becouse of this, try directive work with bugs that so bad for Mino.

I want to create backup of current state of compiler when it meets try directive. If after compiling we have errors - errors clear and this state of compiler replace by backup.

Now 'try' not work only in statements in 'if-else' and loop operators.
