* Test using newer dist on Travis
Since Scintilla needs C++11
* Add debugging code for when configure fails
* Workaround a pkg-config-corsswrapper bug on Ubuntu 14.04

Use a per-line cache to avoid re-computing the offset from the start of
the buffer each time. This dramatically speeds up multiple replacements
on large files.

We cannot compute the length in characters after the text has been
deleted, so we need to compute it in BEFOREDELETE. However, we need to
emit the signal once the buffer has actually changed, so we need to
cache the value in-between those events.
