#299- severity flagging with keywords

[Cubix33]

Closes #299

Added a check that will automatically flag a warning sign if the transcript contains any important keywords such as 'fire', 'hazmat', 'danger'. That way, the admins will automatically know what reports to look into first, and which one to prioritise, or maybe even categorise as important in storage for further future use and reference, and better lookup.
