FMSLogo Code

Merge in change from trunk.

Strip a few more tags from the .CHM
- links home
- lang attributes beyond just "en"
- chapter classes without a language

Merge changes in from trunk (incorporate a Hindi translation)

Fix typo in comment: XLST -> XSLT

Update the translation tables generation to be compatible with Unicode structure:
1) Read names from UTF-8 text files (not header files)
2) Write out XML in ASCII with character entities (not UTF-8)
3) Parse graphics.h expecting a wide text literal

Remove trailing whitespace

Remove unexpected line breaks that were added by using the wrong perl.

Extend the build to support a Hindi translation of FMSLogo.
There is no ANSI code page for Hindi, so only the manual and installer are localizable.

Reword some parts to sound less redundant.

Make it so that position=0 is still the beginning of the file, even if a BOM exists.
Adding Unicode to the File API made READPOS/WRITEPOS more complicated, but keeping 0 as the beginning of the file is important for backward compatibility because it was documented that way.
