This commit entails major changes in the songbook appearance since songs need less vertical space. Advantages:
- saves roughly 100 pages for songbook.pdf !
- less scrolling / page turning required
- better readability due to more important delta between inter-verse spacing and inter-line spacing
- introduce two new options:
- 'url' that links to the artist's website
- 'original' that refers to the original song
- display the album in the song header
- merge patacrep-en.tmpl in patacrep.tmpl
- phantom sections
- translate strings according to \lang parameter
- english book is now based on patacrep template
- merge license-en into license
- the english/french version now depends on the template's lang parameter
- remove trailing spaces
- add phantom section for a reference in the pdf bookmarks
This macro depends on the repeatedchord environment:
- if chords are repeated, acts like the \transpose macro from LaTeX package
- if not, a muscinote information box is displayed with the number of half-steps for transposition
This macro can prove usefull to hide the complexity of songs that transpose their verses (e.g: Barbara - L'aigle noir): in repeatedchords mode, the chords are explicitly displayed (in their transposed form), in norepeatedchords mode, it only provides the information that the verses should be transposed.
