Large-file comparison performance

Fixed a crash comparing files of several gigabytes.
Long file paths. UltraCompare handles paths longer than 260 characters when Windows long paths are enabled.
Horizontal scrolling for long lines, without wrapping.
Encoding detection. Mainframe EBCDIC text files, and other files whose encoding was previously misdetected, are recognized and decoded correctly on load.
Saved compare reports. The Save result output records which ignore options were active.
