#1201 Add GUI aligner tool

[Aaron Madlon-Kay]

OmegaT now offers a GUI alignment tool, accessible via Tools > Align Files. The tool supports all file formats supported by OmegaT. The workflow has two parts:

1. Automated alignment:
   • Text is extracted from the files, segmented, and then given an initial automatic alignment according to algorithms provided by the mALIGNa library.
   • Aligned sentences are grouped together in 1–n relationships, indicated by the row highlighting in the table. A set of contiguous cells sharing the same color will end up squashed to a 1–1 text unit in the final output.
   • The user may tweak algorithm parameters, segmentation rules, file filter settings, etc. to improve the automatic alignment before proceeding.
2. Manual adjustment:
   • The user can manually edit the aligned sentences. Moving up/down, splitting, merging, and editing are supported.
   • Groups can be included or excluded from the final output via the "Keep" checkboxes. Groups where source and target are identical are excluded by default.
   • Groups can be marked as "accepted" or "needs review".
   • Efficiently leverage the alignment algorithm and minimize manual shuffling with Pinpoint Align and Realign Pending:
     1. Identify misaligned regions.
     2. Mark the region's borders (the previous or next correctly aligned groups) as "accepted", or use Edit > Start/End Pinpoint Align (Space key) to create borders.
     3. Automatically realign the not-yet-accepted regions with Edit > Realign Pending (Cmd/Ctrl+R).

When manual adjustment is complete, the user can save the result as TMX.

Other features:

• Customizable regex-based text highlighting to help visually assess alignment. Numbers (\d+) are highlighted by default.
• All editing commands are accessible from the keyboard.
• Emacs-like table navigation keys.
• ID- or path-based alignment for file formats that support it.
• "Parsewise" alignment for files that happen to contain the same number of pre-segmentation entries (e.g. files translated with OmegaT).
• Optionally remove all tags from the text.
