Various manpage fixes and improvements

- Use [<vendor>:]<board>], not [<vendor>:]<part>], which is more clear.

 - Mention TSOP48 chips in the description.

 - Highlight various additional parts in the manpage which were missing
   so far (i.e., make them bold), including cmdline switches and others.

 - Mention that you can use -VV.

 - Fix name of the now-renamed 'Supported mainboards' section in -L output.

 - Mention that ft2232_spi and buspirate_spi only support SPI chips.

 - Readability and cosmetic improvements, add missing escapes, fix typos.
