JavaScript: fix parsing of regular expressions in a return statement
Plug a memory leak

Do not evaluate a macro argument multiple times if it gets passed an
expression, especially if that expression allocates memory.

Thanks to Pavel Roschin for spotting the leak.
Plug a memory leak

Thanks to Pavel Roschin for spotting it.
Fix some module-specific globals not declared static

This prevents the symbol to be exported and possibly conflict with
another one.
Plug a memory leak when reading misnamed tag files

Don't leak the file name if we can't determine to which filetype it
belongs.  Thanks to Pavel Roschin for spotting this.

Also, remove an useless second function indirection that simply made
the code harder to understand.  This will make Matthew happy ;)

Add flag to tm_tags_find() to indicate the tags array may not be sorted

tm_tags_find() relies on a sorted tags array to be passed in but in
tm_source_file_set_tag_arglist() we don't have a sorted array yet and
sorting it on demand seems more heavy than the alternative:
make tm_tags_find() search the array linear if the new flag is set.

This fixes a bug in the Python parser when assigning the argument list
of __init__() methods to their class' argument list which annoyed me
for years already.

Also add a test case for this.
Adjust test case tags file for fixed Python parser (class arglist assignment)
Read filetype's mime type from the configuration files

This allows custom filetypes to define a mime type, hence the icon
displayed for this filetype;  as well as moving ones for built-in
filetypes out of the code to the configuration files.
Use GIcon for the filetype icon rather than rendered pixbuf

This allows to re-use the icon more easily since it's not rendered at
a particular size but simply an icon description.  It also allows for
implicit icon updating when the theme changes if the display code
implements it (and GTK widgets does).
Do not ignore keys inside inherited groups

When inheriting a group in a filetypes file, do not ignore local keys.
This allows for partial overrides of the parent group, like:

	[settings=Parent]
	key=value

All keys from Parent's group "settings" would be imported, but now the
"key" key wouldn't be ignored anymore and would override a "key" key
from the group copied from Parent if it exists.
