- Fix: replace `re.fullmatch()` by `re.search()`
- Validation RE patterns at startup
- Improve output:
- Display `UID`, `RssAnon`, `RssFile`, `RssShmem` and `cmdline` of the victim in corrective action reports
- Display `UID`, `VmSize`, `RssAnon`, `RssFile`, `RssShmem` and `cmdline` of the victim in corrective action reports
- Print in terminal with colors
- Optimize limiting `oom_score_adj`: now it can works without UID=0
- Optimize GUI warnings: find env without run `ps` and `env` (partially implemented)
