As discussed in #410, the previous SF redirect is better replaced by
a redirect on www.geany.org which we can control.
This way we can also quickly change the target URL if it changes at
Paypal.

Since document_compare_by_tab_order_reverse does the exact reverse of
document_compare_by_tab_order the code need not to be duplicated. Instead
document_compare_by_tab_order can be called and the return value be reversed.

Remove "Show macro list" keybinding and feature

This feature looks like a poorly implemented subset of "Complete word",
but lacks some important features like prefix filtering.  It is also
misnamed as it shows not only macros, but also variables and enums.

It also only shows `editor_prefs.autocompletion_max_entries`, but does
so from *each* file, not as a whole.

So drop it altogether, as this feature doesn't really look useful and
the current implementation seem to suffer of too many shortcomings for
it to realistically be actually used.

waf: Don't relink scintilla and geany on every build

The ant_glob() function doesn't return a list of strings but rather
a list of waflib.Node.Nod3 objects. These print as paths so build
works but apparently confuse waf which thinks the files have
changed every time the waf command is performed.

Relinking scintilla and geany on every waf invocation is especially
problemmatic during "sudo waf install" where scintilla and geany
binaries get owned by the root user. This isn't a big problem on Linux
but on OS X this prevents subsequent waf calls to update the
binaries and the build fails.

To fix the issue, just convert the waflib.Node.Nod3 objects
to relative (string) paths.

Currently the R filetype has a rather random collection of keywords.

This commit fixes the primary keywords (as used in RStudio, an IDE
specialized for R), and also adds the appropriate list of built-in
constants.
See https://github.com/rstudio/rstudio/blob/master/src/gwt/acesupport/acemode/r_highlight_rules.js
for the list of keywords used in RStudio.

Furthermore, the commit adds the `.` (dot) to `wordchars`.  In R the
set of symbols which can be used in object names is `[A-Za-z0-9_.]`
(with code portability and platform compatibility in mind).  For more
gruesome details see:
http://cran.r-project.org/doc/manuals/r-release/R-intro.html#R-commands_003b-case-sensitivity-etc
RStudio also treats the dot as part of the "word".
