vim: add gaybuild syntax file 
This is sort of half-finished and probably full
of bugs, but it works for the most part.
At least it's nicer to look at than blank text.

lex: fix incorrect cursor position tracking 
It works.  Finally.  This also fixes a stupid
off-by-one error that made the first token
disappear.

ast: allow definitions in loop head 
This is a rather bad hack, but it makes parsing a
lot easier, so i'll allow it for now.

rt: add initial runtime implementation 
Alright, so this is ugly.  I'm really not happy
with how it turned out for the most part, but
that's what refactoring is for.  For now, though,
i will sleep because i'm seriously tired.

lex: fix erroneous keyword recognition 
I tried to parse a function called
"fn_with_callback" for the upcoming function
support and realized that the lexer mistook the
first two letters for the respective keyword.
So that is fixed now, i guess.

lex: remove ** operator 
I don't think this would be useful, and it would
only complicate parsing due to its right
associativity, so it has to go

ast: refactor and add production rule docs 
As usual, this is nowhere near finished, but it's
a good start.

ast: add expression support 
This adds the basic set of expressions:
assignments, binary/unary expressions, function
calls, and array accesses.  Binary operator
precedence is also taken into account.  What's
still missing are parenthesized expressions, but
those should be easy to do.

lex: fix yet another token position bug 
When skipping whitespace, the token position must
be updated accordingly.  Additionally, the token
position is now updated when creating a new one.
It still doesn't work because something with the
cursor is broken.

rename module to target 
To avoid potential confusion with Rust modules,
gaybuild's modules are now called targets.

cursor: break line after \n 
Up to now, the cursor broke the line *before* the
\n and made that character the 0th one in the new
line.  I don't know why i did this, but at least
it's fixed now.

error: refactor into unified error type 
This is probably a bad idea.  Every stage in the
compiler pipeline will use the same type for
emitting errors now (good), but it's doing so
using a bunch of wrappers (bad, i think).

improve error system 
There is a generic error interface now that will
be used throughout the codebase.

lex: ignore comments 
This is a cheap hack to just omit comments from
the token stream for now.  I doubt they will ever
be used at all, so their existence would just mean
extra work for the parser.

lex: support backwards seeking and more tokens 
The lexer now records every token it encounters
internally such that peeking and other useful
stuff is possible.  Will come in handy for the
parser.  Also, while i was at it, i also added
more primitive tokens like + - * / because i'm
probably gonna need it later anyway.

add lexer and test file 
There are most likely gonna be a lot of changes
until we reach the final syntax, but this is a
good start i think.

add cursor for lexer 
This is a little helper for the lexer so it can
read a stream forwards and backwards.  It will
also keep track of line and column numbers for
better error output.
