Built in symbol decompresser, symbols bug for some BIN files, faster file loading, Biopower symbol names

New: Built-in compressed symbol table expander. Recreated using decode.exe disassembly file and watching/working out what it does using Dosbox debug mode - phew!. Better late than never :-)
***
Fixed: A bug that caused symbols to become out of step in BIN files that had large symbols (specifically > 10,0000 bytes e.g. 'PLT_buffer' in SRAM can be 15,000 Bytes)
***
Changed: 'Only symbols within binary' filter to suit displaying hexadecimal symbol addresses. NOTE: The filter is now disabled by default because no symbols are shown when T7Suite starts up if the filter is enabled (due to an apparent DevExpress filter 'quirk' ???)
***
Enhancement: Faster file loading, was all a bit loopy with loops following loops and loops within loops...
Enhancement: Symbol names for known symbols in BioPower files are now shown in the 'Symbol name' column. The symbol numbers of these symbols is now shown in the 'User description' column.
***
Removed: T7Decode - no longer required
Removed: DOSBOX - no longer required
***
Discovered: An 'Easter Egg' in the 'About' box...
