idLangDict: Workaround for Doom3: Lost Mission stringtables #265

Browse source 
The Doom3: Lost Mission (aka D3LE) mod uses string table entry keys that
don't follow the proper Doom3 scheme of "#str_01234", but look like
"#str_adil_exis_pda_01_audio_info" - the "hash" algorithm of idLangDict,
which basically just converts the number after "#str_" into an int,
probably doesn't work very well with this and there was an assertion
to prevent this..
However, it seems to work well enough, so now I only print one warning
for the first "invalid" key and otherwise accept those keys.

The stringtable (strings/*.lang) also has font-related entries
(like "#font" "Chainlink_Semi-Bold") that triggered another assertion,
now everything that starts with "#font" is silently skipped.
