Fix the regression after 3b34a02: setting readonly option to true
in onBufferOpen lua callback doesn't work, since it is automatically
reset to false if write permission is not denied.
This commit introduces several improvements to the backup system.
* Backups are made every 8 seconds for buffers that have been modified
since the last backup.
* The `permbackup` option allows users to specify that backups should
be kept permanently.
* `The backupdir` option allows users to store backups in a custom
directory.

Ref #1539 (removes possibility of race condition for backups)
This option is disabled by default, and when enabled causes micro
to parse `:line:col` as a location for the cursor rather than
as part of the filename.

There is a bit of mess in the usage of HighlightMatches: in some places
we assume that it updates lines from startline to endline inclusive,
in other places we assume it's non-inclusive.
This fix makes it always inclusive.
In particular, it fixes a bug: when we open a file which has no
newline at the end, the last line isn't highlighted.
If you run micro as `micro | cat` for example, micro will disallow
you from saving the file, and when you quit the buffer, the contents
will be sent to the pipe. This allows one to use micro as part of
an interactive unix pipeline.
Closes#1524
The autosave option is now specified as an integer, which denotes
the number of seconds to wait between saving the file. If the option
is 0, then autosaving is disabled. If the option is given by the user
as a boolean, it will be converted to 8 if true, and 0 if false.
Fixes#1479
This change introduces header files for syntax files. The header
files only contain the filetype and detection info and can be
parsed much faster than parsing a full yaml file. To determine
which filetype a file is, only scanning the headers is necessary
and afterwards only one yaml file needs to be parsed. Use the
make_headers.go file to generate the header files. Micro expects
that all default syntax files will have header files and that
custom user syntax files may or may not have them. Resolving
includes within syntax has not yet been implemented. This
optimization improves startup time.
