* Bicleaner hardrules changes:
* New rule: c_identical_wo_punct to reject sentences only different in punctuation (and it's case insensitive)
* New rule: Sentences containing "Re:" are rejected
* Rule change: c_minimal_length now rejects sentences with both sides <= 3 words (instead of only one)
* Rule change: c_identical and c_identical_wo_digits now is case insensitive
* Rule change: Breadcrumbs rule now split into c_no_breadcrumbs1 and c_no_breadcrumbs2
* Rule change: Breadcrumbs2 now includes character "·" in the rejected characters
* Rule change: c_length now compares byte length ratio (will avoid rejecting valid sentences due to length ratio when comparing languages with different alphabets)
* Changed behaviour for `--annotated_output` argument in hardrules. See README.md for more information.
* New parameter: `--disable_lang_ident` flag to avoid applying rules that need to identify the language
* Bicleaner classify changes:
* Now using only 3 decimal places for Bicleaner score and LM score
* Removed INFO messages when processes starting/ending (except when debugging)
* New parameter: '--disable_hardrules' flag to avoid applying hardrules
* New parameter: '--disable_lang_ident' flag to avoid applying rules that need to identify the language
* New parameter: '--score_only' flag to output only Bicleaner scores (proposed by [kirefu](https://github.com/kirefu))
